The ancient man's DNA "shows that there were indeed modern humans
in the area of those Siberian sites who could have made stone tools," says study coauthor Janet Kelso, a Max Planck paleogeneticist.
In Reassessing Paleolithic subsistence, Morin conducts a detailed analysis of the animal bone remains from the sequence at Saint-Cesaire, which spans the period from the Mousterian of Acheulean Tradition to the Evolved Aurignacian, to explicitly test one explanation for the replacement of Neanderthals by modern humans
The scientists said it was likely there was "at least substantial gene flow" from modern humans
who had settled in regions to the south and west of Tianyuan Cave at an earlier date.
Anthropologists believe these 10 hominids were modern humans
in their primitive stage, likely just after evolving from archaic humans, the first fossilized remains that provide clues to the linkage between paleoanthropic and neanthropic humans.
The new dates suggest that Neandertals and modern humans
(Homo sapiens) simultaneously inhabited Western Europe for 2,600 to 5,400 years.
By examining the different genetic makeup among modern human
populations, the scientists' model was able to infer how much genetic similarity there would have been between distinct populations within a continent.
Bocherens and Drucker explore possible contrasts in Neanderthal and modern human
diets using isotopic signatures.
The oldest known fossil remains of modern humans
were found at the site of an ancient lake near the village of Herto in Ethiopia.
The real facts document something completely different: Anatomically modern human
beings, not distant ape-like ancestors, go back millions of years.
Such a Denisovan genetic stamp isn't found in other modern human
populations, suggesting a unique interbreeding event in Melanesian history that probably took place after a similar genome mingling between Neandertals and non-African modern humans
An international team of researchers including Svante Pbo and Qiaomei Fu of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, sequenced nuclear and mitochondrial DNA that had been extracted from the leg of an early modern human
from Tianyuan Cave near Beijing, China.
Another, more complex scenario is that an African group ancestral to both Neanderthals and certain modern human
populations genetically split from other Africans beginning about 230,000 years ago.
