Homo Sapiens Versus Neanderthals

Explore the origins of modern humans. Fossil evidence from Middle East caves and elsewhere has revealed some competitive advantages modern humans, known as Homo sapiens, are believed to have held over the more archaic human species, Neanderthals. For example, during the time in which the two species may have coexisted, Homo sapiens lived on high ground, from which they could survey the landscape and plan their hunting expeditions. Some scientists have theorized that the success of this strategy may have contributed to the demise of the valley-dwelling Neanderthals, who became extinct about 30,000 years ago. Adapted from NOVA.
