Behavioral modernity is a term used in anthropology, archeology and sociology to refer to a set of traits that distinguish present day humans and their recent ancestors from both other living primates and other extinct hominid lineages. It is the point at which Homo sapiens began to demonstrate a reliance on symbolic thought and to express cultural creativity. These developments are often thought to be associated with the origin of language.
There are two main theories regarding when modern human behavior emerged. One theory holds that behavioral modernity occurred as a sudden event some 50 kya (50,000 years ago) in prehistory, possibly as a result of a major genetic mutation or as a result of a biological reorganization of the brain that led to the emergence of modern human natural languages. Proponents of this theory refer to this event as the Great Leap Forward or the Upper Paleolithic Revolution.
The second theory holds that there was never any single technological or cognitive revolution. Proponents of this view argue that modern human behavior is the result of the gradual accumulation of knowledge, skills and culture occurring over hundreds of thousands of years of human evolution. Proponents of this view include Stephen Oppenheimer in his book Out of Eden, and John Skoyles and Dorion Sagan in their book Up from Dragons: The evolution of human intelligence.
Terence Kemp McKenna (November 16, 1946 – April 3, 2000) was an American philosopher, psychonaut, researcher, teacher, lecturer and writer on many subjects, such as human consciousness, language, psychedelic drugs, the evolution of civilizations, the origin and end of the universe, alchemy, and extraterrestrial beings.
Terence McKenna grew up in Paonia, Colorado. He was introduced to geology through his uncle and developed a hobby of solitary fossil hunting in the arroyos near his home. From this he developed a deep artistic and scientific appreciation of nature.
At age 16, McKenna moved to Los Altos, California to live with family friends for a year. He finished high school in Lancaster, CA. In 1963, McKenna was introduced to the literary world of psychedelics through The Doors of Perception and Heaven and Hell by Aldous Huxley and certain issues of The Village Voice that talked about psychedelics.
McKenna claimed that one of his early psychedelic experiences with morning glory seeds showed him "that there was something there worth pursuing." In an audio interview Terence Mckenna claims to have started smoking cannabis regularly during the summer following his 17th birthday.
