New Insights into Differences in Brain Organization between Neanderthals and Anatomically Modern Humans
," Proceedings of the Royal Society B.
Villa and Roebroeks scrutinized nearly a dozen common explanations for Neanderthal extinction that rely largely on the notion that the Neanderthals were inferior to anatomically modern humans
and found that none of the hypotheses were supported by the available research.
Our analysis indicates this lineage diverged from previously known Y chromosomes about 338,000 ago, a time when anatomically modern humans
had not yet evolved," reports Michael Hammer, associate professor in the Department of Ecology and Evolutionary Biology.
When the out-of-Africa migrations of anatomically modern humans
are taken into consideration, a window is opened that points towards the emergence and nature of such variations and their attendant diseases.
Recent research in Europe, Africa, and Southeast Asia suggests that we can no longer assume a direct and exclusive link between anatomically modern humans
and behavioral modernity (the 'human revolution'), and assume that the presence of either one implies the presence of the other: discussions of the emergence of cultural complexity have to proceed with greater scrutiny of the evidence on a site-by-site basis to establish secure associations between the archaeology present there and the hominids who created it.
Another interesting aspect of the find is that Homo floresiensis apparently lived until at least 18,000 years ago and was, therefore, a contemporary of anatomically modern humans
The first evidence of anatomically modern humans
appears about 150,000 years ago.
In this project, I propose to quantify the extent of local adaptation in Anatomically Modern Humans
by using climate-informed spatial genetic models (CISGeM) to reconstruct past population sizes, local movements, and range expansions, and thus provide a null model against which the signature of geographically-localised selection can be detected.
11 ( ANI ): Researchers have claimed 300,000 years before the emergence of anatomically modern humans
, prehistoric people chose to predominantly live on islands in the flood plains of major rivers.
Anatomically modern humans
have only been around for the last 200,000 years - so you can see it takes a really long time for intelligent life to develop.
