For nearly a century, anthropologists have been debating the relationship of Neanderthals to modern humans. Central to the debate is whether Neanderthals contributed directly or indirectly to the ancestry of the early modern humans that succeeded them.
As this discussion has intensified in the past decades, it has become the central research focus of Erik Trinkaus, Ph.D., professor of anthropology at Washington University in St. Louis. Trinkaus has examined the earliest modern humans in Europe, including specimens in Romania, Czech Republic and France. Those specimens, in Trinkaus' opinion, have shown obvious Neanderthal ancestry.
In an article appearing the week of April 23 in the Proceedings of the National Academy of Sciences, Trinkaus has brought together the available data, which shows that early modern humans did exhibit evidence of Neanderthal traits.
"When you look at all of the well dated and diagnostic early modern European fossils, there is a persistent presence of anatomical features that were present among the Neanderthals but absent from the earlier African modern humans," Trinkaus said. "Early modern Europeans reflect both their predominant African early modern human ancestry and a substantial degree of admixture between those early modern humans and the indigenous Neanderthals."
This analysis, along with a number of considerations of human genetics, argues that the fate of the Neanderthals was to be absorbed into modern human groups. Just as importantly, it also says that the behavioral difference between the groups were small. They saw each other as social equals.
