In the Upper Paleolithic of Eurasia, or the Late Stone Age as it is called in Africa, the archaeological signature stands in strong contrast to that of the Middle Paleolithic/Middle Stone Age.
It was characterized by significant innovation: , on the other hand, proffers the notion that it was probably a biological change brought about by mutations that played the key role in the emergence of behaviorally modern humans.
While these early Hence, the anatomical and paleogeographic evidence suggests that Neanderthals and early modern humans had been isolated from one another and were evolving separately into two distinct species.
Very interestingly, while Neanderthals and early The archaeological picture changed dramatically around 40-50,000 years ago with the appearance of behaviorally modern humans.
However, by 30,000 years ago this taxonomic diversity vanished and humans everywhere had evolved into the anatomically and behaviorally modern form.
The nature of this transformation is the focus of great deliberation between two schools of thought: one that stresses multiregional continuity and the other that suggests a single origin for modern humans.
This is a classic example of geographic isolation leading to a speciation event.
In contrast, at roughly the same time, in Africa, a body plan essentially like our own had appeared.
The stunning change in cultural adaptation was not merely a quantitative one, but one that represented a significant departure from all earlier human behavior, reflecting a major qualitative transformation.For the moment, the majority of anatomical, archaeological and genetic evidence gives credence to the view that fully modern humans are a relatively recent evolutionary phenomenon.The current best explanation for the beginning of modern humans is the Out of Africa Model that postulates a single, African origin for . Johanson, is professor of anthropology and Director of the Institute of Human Origins at Arizona State University.It is, therefore, highly likely that modern humans do not carry Neanderthal genes in their DNA.The chronology in the Middle East does not support the Multiregional Model where Neanderthals and anatomically modern humans overlapped for a long period of time.
