Modern Awash River, Ethiopia, descendant of the Palaeo-Awash, source of the sediments in which the oldest Stone Age tools have been found

The Stone Age is a broad prehistoric period during which stone was widely used in the manufacture of implements with a sharp edge, a point, or a percussion surface. The period lasted roughly 2.5 million years, and ended between 4500 BCE to 2000 BCE with the advent of metalworking. Stone Age artifacts include tools used by humans and by their predecessor species in the genus Homo, as well as the earlier partly contemporaneous genera Australopithecus and Paranthropus. Bone tools were used during this period as well, but are more rarely preserved in the archaeological record. The Stone Age is further subdivided by the types of stone tools in use.

The Stone Age is the first of the three-age system of archaeology, which divides human technological prehistory into three periods:

• The Stone Age
• The Bronze Age
• The Iron Age

Historical significance[link]

The Stone Age is nearly contemporaneous with the evolution of the genus Homo, the only exception possibly being at the very beginning, when species prior to Homo may have manufactured tools. According to the age and location of the current evidence, the cradle of the genus is the East African Rift System, especially toward the north in Ethiopia, where it is bordered by grasslands. The closest relative among the other living Primates, the genus Pan, represents a branch that continued on in the deep forest, where the primates evolved. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia.

Starting from about 3 mya a single biome established itself from South Africa through the rift, North Africa, and across Asia to China, which has been called "transcontinental 'savannahstan'" recently.^[1] Starting in the grasslands of the rift, the ancestors of man found an ecological niche as a tool-maker and developed a dependence on it. Homo erectus, the predecessor of modern humans, became a "tool equipped savanna dweller."^[2]

Beginning of the Stone Age[link]

The oldest known stone tools have been excavated from several sites at Gona, Ethiopia, on the sediments of the paleo-Awash River, which serve to date them. All the tools come from the Busidama Formation, which lies above a disconformity, or missing layer, which would have been from 2.9-2.7 mya. The oldest sites containing tools are dated to 2.6-2.55 mya.^[3] One of the most striking circumstances about these sites is that they are from the Late Pliocene, where previous to their discovery tools were thought to have evolved only in the Pleistocene. Rogers and Semaw, excavators at the locality, point out that:^[4]

"...the earliest stone tool makers were skilled flintknappers .... The possible reasons behind this seeming abrupt transition from the absence of stone tools to the presence thereof include ... gaps in the geological record."

The excavators are confident that more tools will be found elsewhere from 2.9 mya. The species who made the Pliocene tools remains unknown. Fragments of Australopithecus garhi, Australopithecus aethiopicus^[5] and Homo, possibly Homo habilis, have been found in sites near the age of the oldest tools.^[6]

End of the Stone Age[link]

Innovation of the technique of smelting ore ended the Stone Age and began the Age of Metals. The first most significant metal manufactured was bronze, an alloy of copper and tin, each of which was smelted separately. The transition from the Stone Age to the Bronze Age was a period during which modern people could smelt copper, but did not yet manufacture bronze, a time known as the Copper Age, or more technically the Chalcolithic, "copper-stone" age. The Chalcolithic by convention is the initial period of the Bronze Age and is unquestionably part of the Age of Metals. The Bronze Age was followed by the Iron Age. During this entire time stone remained in use in parallel with the metals for some objects, including those also used in the Neolithic, such as stone pottery.

The transition out of the Stone Age occurred between 6000 BCE and 2500 BCE for much of humanity living in North Africa and Eurasia. The first evidence of human metallurgy dates to between the 5th and 6th millennium BCE in the archaeological sites of Majdanpek, Yarmovac and Pločnik (a copper axe from 5500 BCE belonging to the Vincha culture, though not conventionally considered part of the Chalcolithic or "Copper Age", this provides the earliest known example of copper metallurgy.^[7] and the Rudna Glava mine in Serbia. Ötzi the Iceman, a mummy from about 3300 BCE carried with him a copper axe and a flint knife.

In regions such as Subsaharan Africa, the Stone Age was followed directly by the Iron Age. The Middle East and southeastern Asian regions progressed past Stone Age technology around 6000 BCE. Europe, and the rest of Asia became post–Stone Age societies by about 4000 BCE. The proto-Inca cultures of South America continued at a Stone Age level until around 2000 BCE, when gold, copper and silver made their entrance, the rest following later. Australia remained in the Stone Age until the 17th century. Stone tool manufacture continued. In Europe and North America, millstones were in use until well into the 20th century, and still are in many parts of the world.

The concept of Stone Age[link]

The term was never meant to suggest that advancement and time periods in prehistory are only measured by the type of tool material, rather than, for example, social organization, food sources exploited, adaptation to climate, adoption of agriculture, cooking, settlement and religion. Like pottery, the typology of the stone tools combined with the relative sequence of the types in various regions provide a chronological framework for the evolution of man and society. They serve as diagnostics of date, rather than characterizing the people or the society.

Lithic analysis is a major and specialised form of archaeological investigation. It involves the measurement of the stone tools to determine their typology, function and the technology involved. It includes scientific study of the lithic reduction of the raw materials, examining how the artifacts were made. Much of this study takes place in the laboratory in the presence of various specialists. In experimental archaeology, researchers attempt to create replica tools, to understand how they were made. Flintknappers are craftsmen who use sharp tools to reduce flintstone to a flint tool.

A variety of stone tools

In addition to lithic analysis, the field prehistorian utilizes a wide range of techniques derived from multiple fields. The work of the archaeologist in determining the paleocontext and relative sequence of the layers is supplemented by the efforts of the geologic specialist in identifying layers of rock over geologic time, of the paleontological specialist in identifying bones and animals, of the palynologist in discovering and identifying plant species, of the physicist and chemist in laboratories determining dates by the carbon-14, potassium-argon and other methods. Study of the Stone Age has never been mainly about stone tools and archaeology, which are only one form of evidence. The chief focus has always been on the society and the physical people who belonged to it.

Useful as it has been, the concept of the Stone Age has its limitations. The date range of this period is ambiguous, disputed, and variable according to the region in question. While it is possible to speak of a general 'stone age' period for the whole of humanity, some groups never developed metal-smelting technology, so remained in a 'stone age' until they encountered technologically developed cultures. The term was innovated to describe the archaeological cultures of Europe. It may not always be the best in relation to regions such as some parts of the Indies and Oceania, where farmers or hunter-gatherers used stone for tools until European colonisation began.

The archaeologists of the late 19th and early 20th centuries CE, who adapted the three-age system to their ideas, hoped to combine cultural anthropology and archaeology in such a way that a specific contemporaneous tribe can be used to illustrate the way of life and beliefs of the people exercising a specific Stone-Age technology. As a description of people living today, the term stone age is controversial. The Association of Social Anthropologists discourages this use, asserting:^[8]

"To describe any living group as 'primitive' or 'Stone Age' inevitably implies that they are living representatives of some earlier stage of human development that the majority of humankind has left behind. For some, this could be a positive description, implying, for example, that such groups live in greater harmony with nature .... For others, ... 'primitive' is a negative characterisation. For them, 'primitive' denotes irrational use of resources and absence of the intellectual and moral standards of 'civilised' human societies.... From the standpoint of anthropological knowledge, both these views are equally one-sided and simplistic."

The three-stage system[link]

In the 1920s, South African archaeologists organizing the stone tool collections of that country observed that they did not fit the newly detailed Three-Age System. In the words of J. Desmond Clark,^[9]

"It was early realized that the threefold division of culture into Stone, Bronze and Iron Ages adopted in the nineteenth century for Europe had no validity in Africa outside the Nile valley."

Consequently they proposed a new system for Africa, the Three-stage System. Clark regarded the Three-age System as valid for North Africa; in sub-Saharan Africa, the Three-stage System was best.^[10] In practice, the failure of African archaeologists either to keep this distinction in mind, or to explain which one they mean, contributes to the considerable equivocation already present in the literature. There are in effect two Stone Ages, one part of the Three-age and the other constituting the Three-stage. They refer to one and the same artifacts and the same technologies, but vary by locality and time.

The Three-stage System was proposed in 1929 by Astley John Hilary Goodwin, a professional archaeologist, and Clarence van Riet Lowe, a civil engineer and amateur archaeologist, in an article titled "Stone Age Cultures of South Africa" in the journal Annals of the South African Museum. By then, the dates of the Early Stone Age, or Paleolithic, and Late Stone Age, or Neolithic (neo = new), were fairly solid and were regarded by Goodwin as absolute. He therefore proposed a relative chronology of periods with floating dates, to be called the Earlier and Later Stone Age. The Middle Stone Age would not change its name, but it would not mean Mesolithic.^[11]

The duo thus reinvented the Stone Age. In Sub-Saharan Africa, however, it was ended by the intrusion of the Iron Age from the north. The Neolithic and the Bronze Age never occurred. Moreover, the technologies included in those 'stages', as Goodwin called them, were not exactly the same. Since then, the original relative terms have become identified with the technologies of the Paleolithic and Mesolithic, so that they are no longer relative. Moreover, there has been a tendency to drop the comparative degree in favor of the positive: resulting in two sets of Early, Middle and Late Stone Ages of quite different content and chronologies.

By voluntary agreement, archaeologists respect the decisions of the Pan-African Congress of Prehistory, which meets every four years to resolve archaeological business brought before it. Delegates are actually international; the organization takes its name from the topic. Louis Leakey hosted the first one in Nairobi in 1947. It adopted Goodman and Lowe's 3-stage system at that time, the stages to be called Early, Middle and Later.

The problem of the transitions[link]

The problem of the transitions in archaeology is a branch of the general philosophic continuity problem, which examines how discrete objects of any sort that are contiguous in any way can be presumed to have a relationship of any sort. In archaeology the relationship is one of causality. If Period B can be presumed to descend from Period A there must be a boundary between A and B, the A-B boundary. The problem is in the nature of this boundary. If there is no distinct boundary, then the population of A suddenly stopped using the customs characteristic of A and suddenly started using those of B, an unlikely scenario in the process of evolution. More realistically a distinct border period, the A/B transition, existed, in which the customs of A were gradually dropped and those of B acquired. If transitions do not exist, then there is no proof of any continuity between A and B.

The Stone Age of Europe is characteristically in deficit of known transitions. The 19th and early 20th century innovators of the modern three-age system recognized the problem of the initial transition, the "gap" between the Paleolithic and the Neolithic. Louis Leakey provided something of an answer by proving that man evolved in Africa. The Stone Age must have begun there to be carried repeatedly to Europe by migrant populations. The different phases of the Stone Age thus could appear there without transitions. The burden on African archaeologists became all the greater, because now they must find the missing transitions in Africa. The problem is difficult and ongoing.

After its adoption by the First Pan African Congress in 1947, the Three-Stage Chronology was amended by the Third Congress in 1955 to include a First Intermediate Period between Early and Middle, to encompass the Fauresmith and Sangoan technologies, and the Second Intermediate Period between Middle and Later, to encompass the Magosian technology and others. The chronologic basis for definition was entirely relative. With the arrival of scientific means of finding an absolute chronology, the two intermediates turned out to be will-of-the-wisps. They were in fact Middle and Lower Paleolithic. Fauresmith is now considered to be a facies of Acheulean, while Sangoan is a facies of Lupemban.^[12] Magosian is "an artificial mix of two different periods."^[13]

Once seriously questioned, the intermediates did not wait for the next Pan African Congress two years hence, but were officially rejected in 1965 (again on an advisory basis) by Burg Wartenstein Conference #29, Systematic Investigation of the African Later Tertiary and Quarternary,^[14] a prestigious conference in anthropology held by the Wenner-Gren Foundation, at Burg Wartenstein Castle, which it then owned in Austria, attended by the same key scholars that attended the Pan African Congress, including Louis Leakey and Mary Leakey, who was delivering a pilot presentation of her typological analysis of Early Stone Age tools, to be included in her 1971 contribution to Olduvai Gorge, "Excavations in Beds I and II, 1960-1963."^[15]

However, although the Intermediate Periods were gone, the search for the transitions continued.

Chronology[link]

Correlation of temperature and time over the last 5 million years.

In 1859 Jens Jacob Worsaae first proposed a division of the Stone Age into older and younger parts based on his work with Danish kitchen middens that began in 1851.^[16] In the subsequent decades this simple distinction developed into the archaeological periods of today. The major subdivisions of the Three-age Stone Age cross two epoch boundaries on the geologic time scale:

• The geologic Pliocene—Pleistocene boundary (highly glaciated climate)
  • The Paleolithic period of archaeology
• The geologic Pleistocene—Holocene boundary (modern climate)
  • Mesolithic or Epipaleolithic period of archaeology
  • Neolithic period of archaeology

The succession of these phases varies enormously from one region (and culture) to another.

Three-age chronology[link]

The Paleolithic or Palaeolithic (from Greek: παλαιός, palaios, "old"; and λίθος, lithos, "stone" lit. "old stone," coined by archaeologist John Lubbock and published in 1865) is the earliest division of the Stone Age. It covers the greatest portion of humanity's time (roughly 99% of "human technological history,"^[17] where "human" and "humanity" are interpreted to mean the genus Homo), extending from 2.5 or 2.6 million years ago, with the first documented use of stone tools by hominans such as Homo habilis, to the end of the Pleistocene around 10,000 BCE.^[17] The Paleolithic era ended with the Mesolithic, or in areas with an early neolithisation, the Epipaleolithic.

Lower Paleolithic[link]

This is a Mode 1, or Oldowan, stone tool from the western Sahara.

The Lower Paleolithic began in Africa. Toward the end of its African phase it propagated in Eurasia, where it remained long after its termination in Africa. Across the whole range Lower Paleolithic in Eurasia may be contemporaneous with Middle and Upper in regions where it had been but was supplanted.

Oldowan in Africa[link]

The earliest documented stone tools were found in East Africa, manufacturers unknown. They belonged to an industry now known as Oldowan, after the type site of Olduvai Gorge in Tanzania; however, sites in Ethiopia later proved to be older.

The tools were formed by knocking pieces off a river pebble, or stones like it, with a hammerstone to obtain large and small pieces with one or more sharp edges. The original stone is called a core; the resultant pieces, flakes. Typically, but not necessarily, small pieces are detached from a larger piece, in which case the larger piece may be called the core and the smaller pieces the flakes. The prevalent usage, however, is to call all the results flakes, which can be confusing. A split in half is called bipolar flaking.

Consequently the method is often called "core-and-flake". More recently, the tradition has been called "small flake" since the flakes were small compared to subsequent Acheulean tools.^[18]

"The essence of the Oldowan is the making and often immediate use of small flakes."

Another naming scheme is "Pebble Core Technology (PBC)": ^[19]

"Pebble cores are ... artefacts that have been shaped by varying amounts of hard-hammer percussion."

Various refinements in the shape have been called choppers, discoids, polyhedrons, subspheroid, etc. To date no reasons for the variants have been ascertained:^[20]

"From a functional standpoint, pebble cores seem designed for no specific purpose."

However, they would not have been manufactured for no purpose:^[20]

"Pebble cores can be useful in many cutting, scraping or chopping tasks, but ... they are not particularly more efficient in such tasks than a sharp-edged rock ...."

The whole point of their utility is that each is a "sharp-edged rock" in locations where nature has not provided any. There is additional evidence that Oldowan, or Mode 1, tools were utilized in "percussion technology"; that is, they were designed to be gripped at the blunt end and strike something with the edge, from which use they were given the name of choppers. Modern science has been able to detect mammalian blood cells on Mode 1 tools at Sterkfontein, Member 5 East, in South Africa. As the blood must have come from a fresh kill, the tool users are likely to have done the killing and used the tools for butchering. Plant residues bonded to the silicon of some tools confirm the use to chop plants.^[21]

Although the exact species authoring the tools remains unknown, Mode 1 tools in Africa were manufactured and used predominantly by Homo habilis. They cannot be said to have developed these tools or to have contributed the tradition to technology. They continued a tradition of yet unknown origin. As chimpanzees sometimes naturally use percussion to extract or prepare food in the wild, and may use either unmodified stones or stones that they have split, creating an Oldowan tool, the tradition may well be far older than its current record.

Towards the end of Oldowan in Africa a new species appeared over the range of Homo habilis: Homo erectus. The earliest "unambiguous" evidence is a whole cranium, KNM-ER 3733 (a find identifier) from Koobi Fora in Kenya, dated to 1.78 mya.^[22] An early skull fragment, KNM-ER 2598, dated to 1.9 mya, is considered a good candidate also.^[23] Transitions in paleoanthropology are always hard to find, if not impossible, but based on the "long-legged" limb morphology shared by H. habilis and H. rudolfensis in East Africa, an evolution from one of those two has been suggested.^[24]

The most immediate cause of the new adjustments appears to have been an increasing aridity in the region and consequent contraction of parkland savanna, interspersed with trees and groves, in favor of open grassland, dated 1.8-1.7 mya. During that transitional period the percentage of grazers among the fossil species increased from 15-25% to 45%, dispersing the food supply and requiring a facility among the hunters to travel longer distances comfortably, which H. erectus obviously had.^[25] The ultimate proof is the "dispersal" of H. erectus "across much of Africa and Asia, substantially before the development of the Mode 2 technology and use of fire ...."^[24] H. erectus carried Mode 1 tools over Eurasia.

According to the current evidence (which may change at any time) Mode 1 tools are documented from about 2.6 mya to about 1.5 mya in Africa,^[26] and to 0.5 mya outside of it.^[27] The genus Homo is known from H. habilis and H. rudolfensis from 2.3-2.0 mya, with the latest habilis being an upper jaw from Koobi Fora, Kenya, from 1.4 mya. H. erectus is dated 1.8-0.6 mya.^[28]

According to this chronology Mode 1 was inherited by Homo from unknown Hominans, probably Australopithecus and Paranthropus, who must have continued on with Mode 1 and then with Mode 2 until their extinction no later than 1.1 mya. Meanwhile living contemporaneously in the same regions H. habilis inherited the tools around 2.3 mya. At about 1.9 mya H. erectus came on stage and lived contemporaneously with the others. Mode 1 was now being shared by a number of Hominans over the same ranges, presumably subsisting in different niches, but the archaeology is not precise enough to say which.

Oldowan out of Africa[link]

Tools of the Oldowan tradition first came to archaeological attention in Europe, where, being intrusive and not well defined, compared to the Acheulean, they were puzzling to archaeologists. The mystery would be elucidated by African archaeology at Olduvai, but meanwhile, in the early 20th century, the term "Pre-Acheulean" came into use in climatology. C.E.P, Brooks, a British climatologist working in the United States, used the term to describe a "chalky boulder clay" underlying a layer of gravel at Hoxne, central England, where Acheulean tools had been found.^[29] Whether any tools would be found in it and what type was not known. Hugo Obermaier, a contemporary German archaeologist working in Spain, quipped:

"Unfortunately, the stage of human industry which corresponds to these deposits cannot be positively identified. All we can say is that it is pre-Acheulean...."

This uncertainty was clarified by the subsequent excavations at Olduvai; nevertheless, the term is still in use for pre-Acheulean contexts, mainly across Eurasia, that are yet unspecified or uncertain but with the understanding that they are or will turn out to be pebble-tool.^[30]

There are ample associations of Mode 2 with H. erectus in Eurasia. H. erectus — Mode 1 associations are scantier but they do exist, especially in the Far East. One strong piece of evidence prevents the conclusion that only H. erectus reached Eurasia: at Yiron, Israel, Mode 1 tools have been found dating to 2.4 mya,^[31] about 0.5 my earlier than the known H. erectus finds. If the date is correct, either another Hominan preceded H. erectus out of Africa or the earliest H. erectus has yet to be found.

After the initial appearance at Gona in Ethiopia at 2.7 mya, pebble tools date from 2.0 mya at Sterkfontein, Member 5, South Africa, and from 1.8 mya at El Kherba, Algeria, North Africa. The manufacturers had already left pebble tools at Yiron, Israel, at 2.4 mya, Riwat, Pakistan, at 2.0 mya, and Renzidong, South China, at over 2 mya.^[32] The identification of a fossil skull at Mojokerta, Pernung Peninsula on Java, dated to 1.8 mya, as H. erectus, suggests that the African finds are not the earliest to be found in Africa, or that, in fact, erectus did not originate in Africa after all but on the plains of Asia.^[24] The outcome of the issue waits for more substantial evidence. Erectus was found also at Dmanisi, Georgia, from 1.75 mya in association with pebble tools.

Pebble tools are found the latest first in southern Europe and then in northern. They begin in the open areas of Italy and Spain, the earliest dated to 1.6 mya at Pirro Nord, Italy. The mountains of Italy are rising at a rapid rate in the framework of geologic time; at 1.6 mya they were lower and covered with grassland (as much of the highlands still are). Europe was otherwise mountainous and covered over with dense forest, a formidable terrain for warm-weather savanna dwellers. Similarly there is no evidence that the Mediterranean was passable at Gibraltar or anywhere else to H. erectus or earlier hominans. They might have reached Italy and Spain along the coasts.

In northern Europe pebble tools are found earliest at Pakenham, United Kingdom, from 0.65 mya. The last traces are from Kent's Cavern, dated 0.5 mya. By that time H. erectus is regarded as having been extinct; however, a more modern version apparently had evolved, Homo heidelbergensis, who must have inherited the tools.^[33] He also explains the last of the Acheulean in Germany at 0.4 mya.

In the late 19th and early 20th centuries archaeologists worked on the assumptions that a succession of Hominans and cultures prevailed, that one replaced another. Today the presence of multiple hominans living contemporaneously near each other for long periods is accepted as proved true; moreover, by the time the previously assumed "earliest" culture arrived in northern Europe, the rest of Africa and Eurasia had progressed to the Middle and Upper Paleolithic, so that across the earth all three were for a time contemporaneous. In any given region there was a progression from Oldowan to Acheulean, Lower to Upper, no doubt.

Acheulean in Africa[link]

An Acheulean tool, not worked over the entire surface.

The end of Oldowan in Africa was brought on by the appearance of Acheulean, or Mode 2, stone tools. The earliest known instances are in the 1.7-1.6 mya layer at Kokiselei, West Turkana, Kenya.^[23] At Sterkfontein, South Africa, they are in Member 5 West, 1.7-1.4 mya.^[21] The 1.7 is a fairly certain, fairly standard date. Mode 2 is often found in association with H. erectus. It makes sense that the most advanced tools should have been innovated by the most advanced Hominan; consequently, they are typically given credit for the innovation.

A Mode 2 tool is a biface consisting of two concave surfaces intersecting to form a cutting edge all the way around, except in the case of tools intended to feature a point. More work and planning go into the manufacture of a Mode 2 tool. The manufacturer hits a slab off a larger rock to use as a blank. Then large flakes are struck off the blank and worked them into bifaces by hard-hammer percussion on an anvil stone. Finally the edge is retouched: small flakes are hit off with a bone or wood soft hammer to sharpen or resharpen it. The core can be either the blank or another flake. Blanks are ported for manufacturing supply in places where nature has provided no suitable stone.

Although most Mode 2 tools are easily distinguished from Mode 1, there is a close similarity of some Oldowan and some Acheulean, which can lead to confusion. Some Oldowan tools are more carefully prepared to form a more regular edge. One distinguishing criterion is the size of the flakes. In contrast to the Oldowan "small flake" tradition, Acheulean is "large flake:"^[34]

"The primary technological distinction remaining between Oldowan and the Acheulean is the preference for large flakes (>10 cm) as blanks for making large cutting tools (handaxes and cleavers) in the Acheulean."

"Large Cutting Tool (LCT)" has become part of the standard terminology as well.^[20]

In North Africa, the presence of Mode 2 remains a mystery, as the oldest finds are from Thomas Quarry in Morocco at 0.9 mya.^[32] Archaeological attention, however, shifts to the Jordan Rift Valley, an extension of the East African Rift Valley (the east bank of the Jordan is slowly sliding northward as East Africa is thrust away from Africa). Evidence of use of the Nile Valley is in deficit, but Hominans could easily have reached the palaeo-Jordan river from Ethiopia along the shores of the Red Sea, one side or the other. A crossing would not have been necessary, but it is more likely there than over a theoretical but unproven land bridge through either Gibraltar or Sicily.

Meanwhile Acheulean went on in Africa past the 1.0 mya mark and also past the extinction of H. erectus there. The last Acheulean in East Africa is at Olorgesailie, Kenya, dated to about 0.9 mya. Its owner was still H. erectus,^[32] but in South Africa, Acheulean at Elandsfontein, 1.0-0.6 mya, is associated with Saldanha man, classified as H. heidelbergensis, a more advanced, but not yet modern, descendant most likely of H. erectus. The Thoman Quarry Hominans in Morocco similarly are most likely Homo rhodesiensis,^[35] in the same evolutionary status as H. heidelbergensis.

Acheulean out of Africa[link]

Mode 2 is first known out of Africa at 'Ubeidiya, Israel, a site now on the Jordan River, then frequented over the long term (hundreds of thousands of years) by Homo on the shore of a variable-level palaeo-lake, long since vanished. The geology was created by successive "transgression and regression" of the lake^[36] resulting in four cycles of layers. The tools are located in the first two, Cycles Li (Limnic Inferior) and Fi (Fluviatile Inferior), but mostly in Fi. The cycles represent different ecologies and therefore different cross-sections of fauna, which makes it possible to date them. They appear to be the same faunal assemblages as the Ferenta Faunal Unit in Italy, known from excavations at Selvella and Pieterfitta, dated to 1.6-1.2 mya.^[37]

At 'Ubeidiya the marks on the bones of the animal species found there indicate that the manufacturers of the tools butchered the kills of large predators, an activity that has been termed "scavenging."^[38] There are no living floors, nor did they process bones to obtain the marrow. These activities cannot be understood therefore as the only or even the typical economic activity of Hominans. Their interests were selective: they were primarily harvesting the meat of Cervids,^[39] which is estimated to have been available without spoiling for up to four days after the kill.

The majority of the animals at the site were of "Palaearctic biogeographic origin."^[40] However, these overlapped in range on 30-60% of "African biogeographic origin."^[41] The biome was Mediterranean, not savanna. The animals were not passing through; there was simply an overlap of normal ranges. Of the Hominans, H. erectus left several cranial fragments. Teeth of undetermined species may have been H. ergaster.^[42] The tools are classified as "Lower Acheulean" and "Developed Oldowan." The latter is a disputed classification created by Mary Leakey to describe an Acheulean-like tradition in Bed II at Olduvai. It is dated 1.53-1.27 mya. The date of the tools therefore probably does not exceed 1.5 mya; 1.4 is often given as a date. This chronology, which is definitely later than in Kenya, supports the "out of Africa" hypothesis for Acheulean, if not for the Hominans.

From Southwest Asia, as the Levant is now called, the Acheulean extended itself more slowly eastward, arriving at Isampur, India, about 1.2 mya. It does not appear in China and Korea until after 1mya and not at all in Indonesia. There is a discernible boundary marking the furthest extent of the Acheulean eastward before 1 mya, called the Movius Line, after its proposer, Hallam L. Movius. On the east side of the line the small flake tradition continues, but the tools are additionally worked Mode 1, with flaking down the sides.

The cause of the Movius Line remains speculative, whether it represents a real change in technology or a limitation of archeology, but after 1 mya evidence not available to Movius indicates the prevalence of Acheulean. For example, the Acheulean site at Bose, China, is dated 0.803±3K mya.^[43] The authors of this chronologically later East Asian Acheulean remain unknown, as does whether it evolved in the region or was brought in.

There is no named boundary line between Mode 1 and Mode 2 on the west; nevertheless, Mode 2 is equally late in Europe as it is in the Far East. The earliest comes from a rock shelter at Estrecho de Quípar in Spain, dated to greater than 0.9 mya. Teeth from an undetermined Hominan were found there also.^[44] The last Mode 2 in Southern Europe is from a deposit at Fontana Ranuccio near Anagni in Italy dated to 0.45 mya, which is generally linked to Homo cepranensis, a "late variant of H. erectus," a fragment of whose skull was found at Ceprano nearby, dated 0.46 mya.^[45]

Middle Palaeolithic[link]

This period is best known as the era during which the Neanderthals lived in Europe and the Near East (c. 300,000–28,000 years ago). Their technology is mainly the Mousterian, but Neanderthal physical characteristics have been found also in ambiguous association with the more recent Châtelperronian archeological culture in Western Europe and several local industries like the Szeletian in Eastern Europe/Eurasia. There is no evidence for Neanderthals in Africa, Australia or the Americas.

Neanderthals nursed their elderly and practised ritual burial indicating an organised society. The earliest evidence (Mungo Man) of settlement in Australia dates to around 40,000 years ago when modern humans likely crossed from Asia by island-hopping. Evidence for symbolic behavior such as body ornamentation and burial is ambiguous for the Middle Paleolithic and still subject to debate. The Bhimbetka rock shelters exhibit the earliest traces of human life in India, some of which are approximately 30,000 years old.

Upper Palaeolithic[link]

From 50,000 to 10,000 years ago in Europe, the Upper Paleolithic ends with the end of the Pleistocene and onset of the Holocene era (the end of the last ice age). Modern humans spread out further across the Earth during the period known as the Upper Palaeolithic. The Upper Paleolithic is marked by a relatively rapid succession of often complex stone artifact technologies and a large increase in the creation of art and personal ornaments. During period between 35 and 10 kya evolved: from 38 to 30 kya Châtelperronian, 40–28 Aurignacian, 28–22 Gravettian, 22–17 Solutrean, and 18–10 Magdalenian. All of these industries except the Châtelperronian are associated with anatomically modern humans. Authorship of the Châtelperronian is still the subject of much debate.

The Americas were colonised via the Bering land bridge which was exposed during this period by lower sea levels. These people are called the Paleo-Indians, and the earliest accepted dates are those of the Clovis culture sites, some 13,500 years ago. Globally, societies were hunter-gatherers but evidence of regional identities begins to appear in the wide variety of stone tool types being developed to suit very different environments.

Epipalaeolithic/Mesolithic[link]

Main articles: Epipalaeolithic, Mesolithic

The period starting from the end of the last ice age, 10,000 years ago, to around 6,000 years ago was characterized by rising sea levels and a need to adapt to a changing environment and find new food sources. The development of Mode 5 (microlith) tools began in response to these changes. They were derived from the previous Palaeolithic tools, hence the term Epipalaeolithic, or were intermediate between the Paleolithic and the Neolithic, hence the term Mesolithic (Middle Stone Age). The choice of a word depends on exact circumstances and the inclination of the archaeologists excavating the site. Microliths were used in the manufacture of more efficient composite tools, resulting in an intensification of hunting and fishing and with increasing social activity the development of more complex settlements, such as Lepenski Vir. Domestication of the dog as a hunting companion probably dates to this period.

The earliest known battle occurred during the Mesolithic period at a site in Egypt known as Cemetery 117.

Neolithic[link]

The Neolithic, New Stone Age, was approximately characterized by the adoption of agriculture, the shift from food gathering to food producing in itself is one of the most revolutionary changes in human history so-called Neolithic Revolution, the development of pottery, polished stone tools and more complex, larger settlements such as Çatal Hüyük and Jericho. Some of these features began in certain localities even earlier, in the transitional Mesolithic. The first Neolithic cultures started around 7000 BCE in the fertile crescent and spread concentrically to other areas of the world; however, the Near East was probably not the only nucleus of agriculture, the cultivation of maize in Meso-America and of rice in the Far East being others.

Due to the increased need to harvest and process plants, ground stone and polished stone artifacts became much more widespread, including tools for grinding, cutting, and chopping. Skara Brae located on Orkney island off Scotland is one of Europe's best examples of a Neolithic village. The community contains stone beds, shelves and even an indoor toilet linked to a stream. The first large-scale constructions were built, including settlement towers and walls, e.g., Jericho and ceremonial sites, e.g.: Stonehenge. The Ġgantija temples of Gozo in the Maltese archipelago are the oldest surviving free standing structures in the world, erected c. 3600-2500 BCE. The earliest evidence for established trade exists in the Neolithic with newly settled people importing exotic goods over distances of many hundreds of miles.

These facts show that there were sufficient resources and co-operation to enable large groups to work on these projects. To what extent this was a basis for the development of elites and social hierarchies is a matter of on-going debate.^[46] Although some late Neolithic societies formed complex stratified chiefdoms similar to Polynesian societies such as the Ancient Hawaiians, based on the societies of modern tribesmen at an equivalent technological level, most Neolithic societies were relatively simple and egalitarian.^[47] A comparison of art in the two ages leads some theorists to conclude that Neolithic cultures were noticeably more hierarchical than the Paleolithic cultures that preceded them.^[48]

Three-stage chronology[link]

The Earlier or Early Stone Age (ESA)[link]

Acheulean biface from Lake Langano area, Ethiopia.

This period is not to be identified with "Old Stone Age", a translation of Paleolithic, or with Paleolithic, or with the "Earlier Stone Age" that originally meant what became the Paleolithic and Mesolithic. In the initial decades of its definition by the Pan-African Congress of Prehistory, it was parallel in Africa to the Upper and Middle Paleolithic. However, since then Radiocarbon dating has shown that the Middle Stone Age is in fact contemporaneous with the Middle Paleolithic.^[49] The Early Stone Age therefore is contemporaneous with the Lower Paleolithic and happens to include the same main technologies, Oldowan and Acheulean, which produced Mode 1 and Mode 2 stone tools respectively. A distinct regional term is warranted, however, by the location and chronology of the sites and the exact typology.

The Middle Stone Age (MSA)[link]

The Middle Stone Age was a period of African prehistory between Early Stone Age and Late Stone Age. It began around 300,000 years ago and ended around 50,000 years ago.^[50] It is considered as an equivalent of European Middle Paleolithic.^[51] It is associated with anatomically modern or almost modern Homo sapiens. Early physical evidence comes from Omo ^[52] and Herto,^[53] both in Ethiopia and dated respectively at c. 195 ka and at c. 160 ka.

The Later Stone Age (LSA)[link]

The Later Stone Age (LSA, sometimes also called the Late Stone Age) refers to a period in African prehistory. Its beginnings are roughly contemporaneous with the European Upper Paleolithic. It lasts until historical times and thus includes cultures corresponding to Mesolithic and Neolithic in other regions.

Material culture[link]

Tools[link]

Stone tools were made from a variety of stone. For example, flint and chert were shaped (or chipped) for use as cutting tools and weapons, while basalt and sandstone were used for ground stone tools, such as quern-stones. Wood, bone, shell, antler (deer) and other materials were widely used, as well. During the most recent part of the period, sediments (such as clay) were used to make pottery. Agriculture was developed and certain animals were domesticated.

Some species of non-Primates are able to use stone tools, such as the Sea Otter, which breaks Abalone shells with them. Primates can both use and manufacture stone tools. This combination of abilities is more marked in apes and men, but only men, or more generally Hominans, depend on tool use for survival.^[54] The key anatomical and behavioral features required for tool manufacture, which are possessed only by Hominans, are the larger thumb and the ability to hold by means of an assortment of grips.^[55]

Food and drink[link]

Food sources of the Palaeolithic hunter-gatherers were wild plants and animals harvested from the environment. They liked animal organ meats, including the livers, kidneys and brains. Large seeded legumes were part of the human diet long before the agricultural revolution, as is evident from archaeobotanical finds from the Mousterian layers of Kebara Cave, in Israel.^[56] Moreover, recent evidence indicates that humans processed and consumed wild cereal grains as far back as 23,000 years ago in the Upper Paleolithic.^[57]

Near the end of the Wisconsin glaciation, 15,000 to 9,000 years ago, mass extinction of Megafauna such as the Wooly mammoth occurred in Asia, Europe, North America and Australia. This was the first Holocene extinction event. It possibly forced modification in the dietary habits of the humans of that age and with the emergence of agricultural practices, plant-based foods also became a regular part of the diet. A number of factors have been suggested for the extinction: certainly over-hunting, but also deforestation and climate change.^[58] The net effect was to fragment the vast ranges required by the large animals and extinguish them piecemeal in each fragment.

During the last glacial, clans hunted herds of bison, horses, reindeer and mammoths that roamed the tundra and grasslands. At first they used stone axes and wooden spears. Later, spears with bone or flint barbs were developed, and spear-throwers were used to throw the spear further and harder. Animals were attacked directly or caught in pitfall traps or snares. Alternatively, a whole herd might be chased over a cliff or into an ambush. This was a good way to build up a large supply of meat. As forests spread over the land, forest animals were hunted with bows and arrows. By about 12,000 BCE, hunters were using tame dogs to help in the chase. Every part of a kill was used. The meat was cooked for food or dried to preserve it. Hides were made into clothes and animal fat was used in lamps. Bones and antlers were made into tools and weapons.

Shelter and habitat[link]

Around 2 million years ago, Homo habilis is believed to have constructed the first man-made structure in East Africa, consisting of simple arrangements of stones to hold branches of trees in position. A similar stone circular arrangement believed to be around 380 thousand years old was discovered at Terra Amata, near Nice, France. (Concerns about the dating have been raised, see Terra Amata). Several human habitats dating back to the Stone Age have been discovered around the globe, including:

• A tent-like structure inside a cave near the Grotte du Lazaret, Nice, France.
• A structure with a roof supported with timber, discovered in Dolni Vestonice, The Czech Republic, dates to around 23,000 BCE. The walls were made of packed clay blocks and stones.
• Many huts made of mammoth bones were found in Eastern Europe and Siberia. The people who made these huts were expert mammoth hunters. Examples have been found along the Dniepr river valley of Ukraine, including near Chernihiv, in Moravia, Czech Republic and in southern Poland.
• An animal hide tent dated to around 15000 to 10000 BCE, in the Magdalenian, was discovered at Plateau Parain, France.
• Megalithic tombs, multichambered, and dolmens, single-chambered, were graves with a huge stone slab stacked over other similarly large stone slabs; they have been discovered all across Europe and Asia and were built in the Neolithic and the Bronze Age.

Art[link]

Prehistoric art is visible in the artifacts. Prehistoric music is inferred from found instruments, while parietal art can be found on rocks of any kind. The latter are petroglyphs and rock paintings. The art may or may not have had a religious function.

Petroglyphs[link]

Petroglyphs appeared in the Neolithic. A Petroglyph is an intaglio abstract or symbolic image engraved on natural stone by various methods, usually by prehistoric peoples. They were a dominant form of pre-writing symbols. Petroglyphs have been discovered in different parts of the world, including Asia (Bhimbetka, India), North America (Death Valley National Park), South America (Cumbe Mayo, Peru), and Europe (Finnmark, Norway).

Rock paintings[link]

A rock painting at Bhimbetka, India, a World heritage site

A modern interpretation of the bison from the Altamira cave ceiling, one of the most famous paintings in the cave.

In paleolithic times, mostly animals were painted, in theory ones that were used as food or represented strength, such as the rhinoceros or large cats (as in the Chauvet Cave). Signs such as dots were sometimes drawn. Rare human representations include handprints and half-human/half-animal figures. The Cave of Chauvet in the Ardèche département, France, contains the most important cave paintings of the paleolithic era, dating from about 31,000 BCE. The Altamira cave paintings in Spain were done 14,000 to 12,000 BCE and show, among others, bisons. The hall of bulls in Lascaux, Dordogne, France, dates from about 15,000 to 10,000 BCE.

The meaning of many of these paintings remains unknown. They may have been used for seasonal rituals. The animals are accompanied by signs that suggest a possible magic use. Arrow-like symbols in Lascaux are sometimes interpreted as calendar or almanac use, but the evidence remains interpretative.^[59]

Some scenes of the Mesolithic, however, can be typed and therefore, judging from their various modifications, are fairly clear. One of these is the battle scene between organized bands of archers. For example, "the marching Warriors," a rock painting at Cingle de la Mola, Castellón in Spain, dated to about 7,000–4,000 BCE, depicts about 50 bowmen in two groups marching or running in step toward each other, each man carrying a bow in one hand and a fistful of arrows in the other. A file of five men leads one band, one of whom is a figure with a "high crowned hat." In other scenes elsewhere, the men wear head-dresses and knee ornaments but otherwise fight nude. Some scenes depict the dead and wounded, bristling with arrows.^[60] One is reminded of Ötzi the Iceman, a Copper Age mummy revealed by an Alpine melting glacier, who collapsed from loss of blood due to an arrow wound in the back.

Stone Age rituals and beliefs[link]

Modern studies and the in-depth analysis of finds dating from the Stone Age indicate certain rituals and beliefs of the people in those prehistoric times. It is now believed that activities of the Stone Age humans went beyond the immediate requirements of procuring food, body coverings, and shelters. Specific rites relating to death and burial were practiced, though certainly differing in style and execution between cultures.^{[citation needed]}

Modern popular culture and the Stone Age[link]

Imaginative depiction of the Stone Age, by Viktor Vasnetsov.

The image of the caveman is commonly associated with the Stone Age. For example, the 2003 documentary series showing the evolution of humans through the Stone Age was called Walking with Cavemen, although only the last programme showed humans living in caves. While the idea that human beings and dinosaurs coexisted is sometimes portrayed in popular culture in cartoons, films and computer games, such as The Flintstones, One Million Years B.C. and Chuck Rock, the notion of hominids and non-avian dinosaurs co-existing is not supported by any scientific evidence.

Other depictions of the Stone Age include the best-selling Earth's Children series of books by Jean M. Auel, which are set in the Paleolithic and are loosely based on archaeological and anthropological findings. The 1981 film Quest for Fire by Jean-Jacques Annaud tells the story of a group of neanderthals searching for their lost fire. A twenty first century series, "Chronicles of Ancient Darkness" by Michelle Paver tells of two New Stone Age children fighting to fulfill a prophecy and save their Clans from the evil Soul Eaters.

A reference to the Stone Age was made by then Chief of Staff, US Air Force General Curtis E. Lemay, when in 1965, he made the statement concerning the North Vietnamese, during the Vietnam War; "They've got to draw in their horns and stop their aggression, or we're going to bomb them back into the stone age." The gist of that statement implies a fierce aerial bombardment intended to utterly destroy the nation's infrastructure, forcing its survivors to revert to primitive technology in order to survive. The same concerns over a nuclear attack impelled the construction of bomb shelters, underground headquarters and caches for food and water during the 1950s.

Sir Elton Hercules John, CBE (born Reginald Kenneth Dwight on 25 March 1947) is an English rock singer-songwriter, composer, pianist and occasional actor. He has worked with lyricist Bernie Taupin as his songwriter partner since 1967; they have collaborated on more than 30 albums to date.

In his four-decade career John has sold more than 250 million records, making him one of the most successful artists of all time.^[1] His single "Candle in the Wind 1997" has sold over 33 million copies worldwide, and is the best selling single in Billboard history.^[2] He has more than 50 Top 40 hits, including seven consecutive No. 1 US albums, 56 Top 40 singles, 16 Top 10, four No. 2 hits, and nine No. 1 hits. He has won six Grammy Awards, four Brit Awards, an Academy Award, a Golden Globe Award and a Tony Award. In 2004, Rolling Stone ranked him Number 49 on its list of the 100 greatest artists of all time.^[3]

John was inducted into the Rock and Roll Hall of Fame in 1994.^[4] Having been named a Commander of the Order of the British Empire in 1996, John received a knighthood from Queen Elizabeth II for "services to music and charitable services" in 1998.^[5]

He has been heavily involved in the fight against AIDS since the late 1980s.^[6] In 1992, he established the Elton John AIDS Foundation and a year later began hosting the annual Academy Award Party, which has since become one of the most high-profile Oscar parties in the Hollywood film industry. Since its inception, the foundation has raised over $200 million.^[7]

John entered into a civil partnership with David Furnish^[8] on 21 December 2005 and continues to be a champion for LGBT social movements. In 2008, Billboard magazine ranked him as the most successful male solo artist on "The Billboard Hot 100 Top All-Time Artists" (third overall, behind only The Beatles and Madonna).^[9]

Life and career[link]

Early life[link]

John was born Reginald Kenneth Dwight on 25 March 1947, the eldest child of Stanley and only child of Sheila Eileen Dwight (née Harris)^[10][11][12] and was raised in Pinner, Middlesex in a council house of his maternal grandparents. His parents did not marry until he was 6 years old, when the family moved to a nearby semi-detached house.^[13][14][15] He was educated at Pinner Wood Junior School, Reddiford School and Pinner County Grammar School, until age 17, when he left just prior to his A Level examinations to pursue a career in the music industry.^[16][17][18]

When John began to seriously consider a career in music, his father, who served as a Flight Lieutenant in the Royal Air Force, tried to steer him toward a more conventional career, such as banking.^[16] John has stated that his wild stage costumes and performances were his way of letting go after such a restrictive childhood.^[18] Both of John's parents were musically inclined, his father having been a trumpet player with the Bob Millar Band, a semi-professional big band that played at military dances.^[18] The Dwights were keen record buyers, exposing John to the popular singers and musicians of the day, and John remembers being immediately hooked on rock and roll when his mother brought home records by Elvis Presley and Bill Haley & His Comets in 1956.^[16][17]

John started playing the piano at the age of 3, and within a year, his mother heard him picking out Winifred Atwell's "The Skater's Waltz" by ear.^[16][17] After performing at parties and family gatherings, at the age of 7 he took up formal piano lessons. He showed musical aptitude at school, including the ability to compose melodies, and gained some notoriety by playing like Jerry Lee Lewis at school functions. At the age of 11, he won a junior scholarship to the Royal Academy of Music. According to one of his instructors, John promptly played back, like a "gramophone record", a four-page piece by Handel that he heard for the first time.^[17]

For the next five years he attended Saturday classes at the Academy in central London, and has stated that he enjoyed playing Chopin and Bach and singing in the choir during Saturday classes, but that he was not otherwise a diligent classical student.^[17] "I kind of resented going to the Academy", he says. "I was one of those children who could just about get away without practising and still pass, scrape through the grades."^[17] He even claims that he would sometimes skip classes and just ride around on the Tube.^[17] However, several instructors have testified that he was a "model student", and during the last few years he was taking lessons from a private tutor in addition to his classes at the Academy.^[17]

John's mother, though also strict with her son, was more vivacious than her husband, and something of a free spirit. With Stanley Dwight uninterested in his son and often physically absent, John was raised primarily by his mother and maternal grandmother. When his father was home, the Dwights would have terrible arguments that greatly distressed their son.^[17] When John was 14, they divorced.^[19] His mother then married a local painter, Fred Farebrother, a caring and supportive stepfather whom John affectionately referred to as "Derf", his first name in reverse.^[17] They moved into flat No. 1A in an eight-unit apartment building called Frome Court, not far from both previous homes. It was there that John would write the songs that would launch his career as a rock star; he would live there until he had four albums simultaneously in the American Top 40.^[20]

Pub pianist to staff songwriter (1962–1969)[link]

At the age of 15, with the help of his mother and stepfather, Reginald Dwight became a weekend pianist at a nearby pub, the Northwood Hills Hotel, playing Thursday to Sunday nights for £35 a week and tips.^[21][22] Known simply as "Reggie", he played a range of popular standards, including songs by Jim Reeves and Ray Charles, as well as songs he had written himself.^[23][24] A stint with a short-lived group called the Corvettes rounded out his time.^[17]

In 1964, Dwight and his friends formed a band called Bluesology. By day, he ran errands for a music publishing company; he divided his nights between solo gigs at a London hotel bar and working with Bluesology. By the mid-1960s, Bluesology was backing touring American soul and R&B musicians like The Isley Brothers, Major Lance, Billy Stewart, Doris Troy and Patti LaBelle and The Bluebelles. In 1966, the band became musician Long John Baldry's supporting band and played 16 times at The Marquee Club.^[25]

After failing lead vocalist auditions for King Crimson and Gentle Giant, Dwight answered an advertisement in the New Musical Express placed by Ray Williams, then the A&R manager for Liberty Records.^[26] At their first meeting, Williams gave Dwight a stack of lyrics written by Bernie Taupin, who had answered the same ad. Dwight wrote music for the lyrics, and then mailed it to Taupin, beginning a partnership that still continues^[update]. When the two first met in 1967 they recorded what would become the first Elton John/Bernie Taupin song: "Scarecrow". Six months later Dwight was going by the name "Elton John" in homage to Bluesology saxophonist Elton Dean and Long John Baldry.^[23]

The team of John and Taupin joined Dick James's DJM Records as staff songwriters in 1968, and over the next two years wrote material for various artists, like Roger Cook and Lulu.^[27] Taupin would write a batch of lyrics in under an hour and give it to John, who would write music for them in half an hour, disposing of the lyrics if he couldn't come up with anything quickly.^[27] For two years, they wrote easy-listening tunes for James to peddle to singers. Their early output included a contender for the British entry for the Eurovision Song Contest in 1969, for Lulu, called "Can't Go On (Living Without You)". It came sixth of six songs. In 1969, John provided piano for Roger Hodgson on his first released recording, the single "Mr. Boyd" by Argosy, a quartet that was completed by Caleb Quaye and Nigel Olsson.^[28][29]
