Neanderthals were apparently no match for the technologically advanced fully modern humans who invaded Europe and evidence for interbreeding of these two types of hominids is equivocal.
Investigation of the patterns of genetic variation in modern human populations supports the view that the origin of who migrated into Europe.
As these peoples migrated they replaced all other human populations with little or no interbreeding.
To understand this controversy, the anatomical, archaeological, and genetic evidence needs to be evaluated.
His biologically based explanation implies that a major neural reorganization of the brain resulted in a significant enhancement in the manner in which the brain processed information.
This is a difficult hypothesis to test since brains do not fossilize.
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 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.
It was literally a “creative explosion” which exhibited the “technological ingenuity, social formations, and ideological complexity of historic hunter-gatherers.” This human revolution is precisely what made us who we are today.
The appearance of fully modern behavior apparently occurred in Africa earlier than anywhere else in the Old World, but spread very quickly, due to population movements into other geographical regions.
Lucy is estimated to have lived 3.2 million years ago.

This is a classic example of geographic isolation leading to a speciation event.
