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.Sometime prior to 1 million years ago early hominids, sometimes referred to as , exited Africa and dispersed into other parts of the Old World.Living in disparate geographical areas their morphology became diversified through the processes of genetic drift and natural selection.There are two theories about the origin of modern humans: 1) they arose in one place—Africa—and 2) premodern humans migrated from Africa to become modern humans in other parts of the world.Most evidence points to the first theory because Lucy is the common name of an Australopithecus afarensis specimen discovered in 1974 in Ethiopia.The Upper Paleolithic lifestyle, as it was called, was based essentially on hunting and gathering.So successful was this cultural adaptation that until roughly 11,000 years ago, hominids worldwide were subsisting essentially as hunter-gatherers.
To understand this controversy, the anatomical, archaeological, and genetic evidence needs to be evaluated.
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.
But it is significant that no changes are seen in the shape of the skulls between earlier and later .
It can only be surmised from the archaeological record, which contains abundant evidence for ritual and art, that these Upper Paleolithic/Late Stone Age peoples possessed language abilities equivalent to our own.
