A central question in the study of human evolution pertains to when, and of course how and why, modern human cognitive abilities evolved beyond those of our ape progenitors. New research sheds light on the timing of this process. In a just published article in the journal Science , an international team of researchers, led by Marcia S. This is significant because the earliest known members of the genus Homo date back a million years earlier, to approximately 2. These earlier humans had already dispersed out of Africa into Eurasia by 2. Therefore, this new research indicates that the first migration of humans into Eurasia was accomplished by populations not possessing modern human cognitive skills, later to be followed by more modern humans, also coming from Africa. For obvious reasons, the behavior and cognitive abilities of extinct humans cannot be directly observed. Scientists must rely on proxy measures, including artifacts and physical anatomy, to infer these characteristics. Both have limitations, however. The material remains in the archaeological record for early humans consists almost exclusively of stone tools, while artifacts, food remains and other objects composed of organic materials have largely disappeared.

Neanderthals are known from numerous fossils, especially from afteryears ago. Accommodation: They lived in Eurasia Anatomical Body Metrics: Average Neanderthal men stood around cm 5 ft 5 in and women cm 5 ft tall, similar to pre - industrial modern humans. Brain Anatomy: The braincases of Neanderthal men and women averaged about 1, cm3 98 cu in and 1, cm3 79 cu in respectively, which is within the range of the values for modern humans.]
