Starting in Africa with our early hominin relatives (who are more closely related to us than to chimpanzees), visitors will travel forward in time to meet our ancient human relatives as they spread into Europe and Asia. The journey ends with modern humans as the only surviving human species in the world today.
Sexual dimorphism in body size is often used as a correlate of social and reproductive behavior in Australopithecus afarensis. In addition to a number of isolated specimens, the sample for this species includes two small associated skeletons (A.L. 288-1 or “Lucy” and A.L. 128/129) and a geologically contemporaneous death assemblage of several larger individuals (A.L. 333). These have driven both perceptions and quantitative analyses concluding that Au. afarensis was markedly dimorphic. The Template Method enables simultaneous evaluation of multiple skeletal sites, thereby greatly expanding sample size, and reveals that A. afarensis dimorphism was similar to that of modern humans. A new very large partial skeleton (KSD-VP-1/1 or “Kadanuumuu”) can now also be used, like Lucy, as a template specimen. In addition, the recently developed Geometric Mean Method has been used to argue that Au. afarensis was equally or even more dimorphic than gorillas. However, in its previous application Lucy and A.L. 128/129 accounted for 10 of 11 estimates of female size. Here we directly compare the two methods and demonstrate that including multiple measurements from the same partial skeleton that falls at the margin of the species size range dramatically inflates dimorphism estimates. Prevention of the dominance of a single specimen’s contribution to calculations of multiple dimorphism estimates confirms that Au. afarensis was only moderately dimorphic.
Prior to agriculture, humans lived happier, healthier, freer and easier lives, claims one of the world’s top scientists and thinkers. In an article published in Discover Magazine nearly 20 years ago, Pulitzer Prize winning anthropologist and evolutionary biologist Jared Diamond calls agriculture “a catastrophe from which we have never recovered.” …
A new study suggests that Neanderthals across Europe may well have been infected with diseases carried out of Africa by waves of anatomically modern humans, or Homo sapiens. As both were species of hominin, it would hav
Two mysterious stone rings found deep inside a French cave were probably built by Neanderthals about 176,500 years ago, proving that the ancient cousins of humans were capable of more complex behavior than previously thought
Des humains occupaient déjà les grottes européennes il y a 176 500 ans, bien avant l’arrivée d’Homo sapiens ! La datation de stalagmites cassées puis agencées en rond dans la grotte de Bruniquel apporte une preuve formelle que l’homme de Néandertal y entretenait des feux, voire y pratiquait des comportements rituels.
Two hundred and fifty-two million years ago, a series of Siberian volcanoes erupted and sent the Earth into the greatest mass extinction of all time. As a result of this mass extinction, known as the Permo-Triassic Mass Extinction
A research team co-led by a scientist at New Zealand's University of Otago has sequenced the first complete mitochondrial genome of a 2500-year-old Phoenician dubbed the "Young Man of Byrsa" or "Ariche".
La grotte du Tarn-et-Garonne prouve que, 140 000 ans avant Chauvet, l’homme de Néandertal s'aventurait dans le monde souterrain à l’aide de torches pour y installer de mystérieuses et savantes structures de stalagmites.
Une équipe de chercheurs de France et de Belgique ont fait une découverte capitale sur l'histoire de l'homme. Des preuves d'habitation de l'homme ont été découvertes dans la grotte de Bruniquel (Tarn-et-Garonne). Celles-ci datent d'environ 176 500 ans, pendant la période de l'homme de Néandertal. Jusqu'à présent, la preuve la plus ancienne d'habitation dans une grotte, la grotte Chauvet (Ardèche) datait d'il y a 38 000 ans.
En Espagne, des gravures d'animaux ont été retrouvées par une équipe d'archéologues près de la ville de Bilbao, dans la grotte d'Atxurra. Les dessins dateraient de l'époque de la fin du Paléolithique supérieur.
