BBC Origins of Us Ep3: Brains ¦ 720p [1/4]
In the final episode Dr Alice Roberts explores how our species, homo sapiens, developed our large brain; and asks why we are the only one of our kind left on the planet today? The evolution of the human mind is one of the greatest mysteries. We are special because of our extraordinary brain, and to understand why we think and act the way we do, we need to look at where and why our brains evolved. The Rift Valley in Kenya is thought to be the crucible of human evolution, and here Alice examines the fossils in our family tree which reveal our brains have more than quadrupled in size since our ancestors split from chimpanzees. Drawing on research on social politics in chimpanzees, the cognitive development of children and the tools that have been found littered across the Rift Valley, Alice explores how and why our ancestors brains became so big. It's thought their need to understand each other and share knowledge has fundamentally shaped the brains we live with today. But our big brains came at a cost. Alice visits a maternity hospital to explore how our difficulties in giving birth are a result of our large brained babies, and travels to meet the women of the Hadza tribe to explore how looking after our large-brained children has shaped the life histories of all of us. Research suggests old age isn't a consequence of modern medicine, but an evolutionary adaptation to allow grandmothers to help raise their grandchildren.

Neanderthals and Neurodiversity [Draft 10]
A draft of a 2-hour video presentation that I'm still putting the finishing touches on. Here is the 10-minute overview: www.youtube.com A PDF I compiled to better explain this: docs.google.com Autism: The Eusocial Hominid Hypothesis Abstract: ASDs (autism spectrum disorders) are hypothesized as one of many adaptive human cognitive variations that have been maintained in modern populations via multiple genetic and epigenetic mechanisms. Introgression from "archaic" hominids (adapted for less demanding social environments) is conjectured as the source of initial intraspecific heterogeneity because strict inclusive fitness does not adequately model the evolution of distinct, copy-number sensitive phenotypes within a freely reproducing population. Evidence is given of divergent encephalization and brain organization in the Neanderthal (including a ~1520 cc cranial capacity, larger than that of modern humans) to explain the origin of the autism subgroup characterized by abnormal brain growth. Autism and immune dysfunction are frequently comorbid. This supports an admixture model in light of the recent discovery that MHC alleles (genes linked to immune function, mate selection, neuronal "pruning," etc.) found in most modern human populations come from "archaic" hominids. Mitochondrial dysfunction, differential fetal androgen exposure, lung abnormalities, and hypomethylation/CNV due to hybridization are also presented as evidence.

NEMS News Fan us on Facebook: www.facebook.com European and Asian Genomes Have Traces of Neanderthal Migrating humans interbred with Neanderthals after leaving Africa. Rex Dalton The genomes of most modern humans are 1--4% Neanderthal — a result of interbreeding with the close relatives that went extinct 30000 years ago, according to work by an international group of researchers. The team, led by Svante Pääbo, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, is reporting only 60% of the Neanderthal genome. But sequencing even this much of the genome was thought to be impossible just a decade ago. "This will change our view of humanity," says John Hardy, a neuroscientist at University College London who was not involved in the research but studies genetic neurodegenerative diseases. The drive to sequence the complete Neanderthal genome began about five years ago following the invention of better, faster methods for sequencing DNA. From three Neanderthal bones found in Vindija Cave in Croatia, the team extracted a total of about 300 milligrams of bone. The bones date to between 38300 and 44400 years ago, and some have been broken open possibly to remove their marrow — a sign of cannibalism. Read More@ www.nature.com

homme de Néandertal
homme de Néandertal
Un homme de Néandertal ou Néandertalien est un représentant fossile du genre Homo qui a vécu en Europe et en Asie occidentale au Paléolithique moyen, entre environ 250 000 et 28 000 ans avant le présent. Durant plus d'un siècle à compter de sa découverte, les hypothèses émises à son sujet ont reflété les préjugés du moment : longtemps considéré comme une sous-espèce au sein de l'espèce Homo sapiens, nommée par conséquent Homo sapiens neanderthalensis, il fut ensuite considéré par la majorité des auteurs comme une espèce indépendante nommée Homo neanderthalensis. En 2010, le séquençage partiel de l'ADN nucléaire néandertalien par une équipe coordonnée par Svante Pääbo pourrait démontrer un métissage ancien entre les hommes de Néandertal et les humains anatomiquement modernes en Eurasie1. Ces résultats remettent en question l'idée selon laquelle ces deux groupes correspondent à des espèces distinctes2,3. Premier homme fossile reconnu, premier être humain disparu distinct de l'Homme actuel, l'homme de Néandertal est à l'origine d'une riche culture matérielle appelée Moustérien ainsi que des premières préoccupations esthétiques et spirituelles en Europe (sépultures). Après une difficile reconnaissance, l'homme de Néandertal a longtemps pâti d'un jugement négatif par rapport aux Homo sapiens. Il est encore considéré dans l'imagerie populaire comme un être simiesque, fruste, laid et attardé. Les progrès de l'archéologie préhistorique et de la paléoanthropologie depuis les <b>...</b>

Tomorrow Today | Genetic Research
Scientists at the Max Planck Institute of Evolutionary Anthropology in Leipzig have been carrying out tests on genetic material taken from fossilized Neanderthal remains. They aim to use genome comparisons to answer some central questions: what's the difference between modern Homo sapiens and Neanderthal - and what makes a human what he or she is?Geneticist Svante Pääbo and his team analysed the 30000 years old DNA sample and identified about 60 percent of the full Neanderthal genome. The researchers now want to compare the results with human genome data. They are particularly curious about why Neanderthal died out tens of thousands years ago, whereas modern humans continued to evolve. Svante Pääbo: "Neanderthals show us how unique WE are. This project isn't primarily about understanding Neanderthals. It's actually more about understanding ourselves and our history." It'll be another two years before the Neanderthal genetic code is completely cracked - and reveals some of humanity's deepest secrets.

From an important fragment of evidence found at: www.youtube.com Together with fragments of the original article of 2010 published in Science Remember the old and wise voices: "If one believes that man was created, human degeneration is as likely as human improvement", "perfectly valid alternatives are ignored", "the evidence amply supported by comparatively recent historical events, is that primitivism and barbarism are not necessarily the earliest stages of man's condition that are more probably the result of degeneration..." (Preface); ..."Niebuhr, in attacking the progressionists of the 18th century, had been one of the first to make the point "that no single example can be brought forward of an actually savage people having independently become civilized" (Tylor, Edward B., Primitive Culture, Vol. I, Murray, London, 2nd ed., Tylor, EB, Anthropology, Hill and Co., NY, 1904, pp. 14, 15, a seminal work on it: Whately, Archbishop of Dublin, "On the Origin of Civilization," Exeter Hall Papers, 1854, 55, Nisbet, London, p. 23.

Wissenschaftler vom Max-Planck-Institut für evolutionäre Anthropologie in Dresden haben das Erbmaterial des Neandertalers untersucht. Durch Gen-Vergleich wollen sie eine zentrale Frage klären: Was unterscheidet Mensch und Neandertaler - und welche Erbanlagen führten zur Entwicklung des modernen Menschen?Den Genforschern aus Leipzig ist es gelungen, aus 30.000 Jahre alten Knochen Erbsubstanz zu gewinnen: die DNA des Neandertalers. Der Genetiker Svante Pääbo und sein Team haben die DNA analysiert - 60 Prozent des gesamten Neandertaler-Genoms: "Wir haben ungefähr 1½ Millionen DNA- Fragmente von Neandertalerknochen gesammelt. Mit Hilfe eines Gerätes bestimmen wir dann die Sequenz, die DNA-Sequenz von jedem dieser Fragmente." Diese Sequenzstücke wollen die Forscher jetzt mit den DNA-Daten des Menschen vergleichen. Sie möchten klären, warum der Neandertaler vor 30.000 Jahren ausgestorben ist, der Mensch sich aber weiterentwickelt hat. Svante Pääbo: "Was der Neandertaler uns jetzt beibringt ist, was uns einzigartig macht. Das Projekt hier geht eigentlich in erster Linie nicht darum, den Neandertaler zu verstehen, sondern in erster Linie, uns zu verstehen und unsere Geschichte." In zwei Jahren soll das Erbgut des Neandertalers komplett entschlüsselt sein - und mehr darüber verraten, was den Menschen zum Menschen macht.
