Prehistoric Homo sapiens not only made and used stone tools, they also specialized them and made a variety of smaller, more complex, refined and specialized toolsВ includingВ composite stone tools,В fishhooks and harpoons, bows and arrows, spear throwers and sewing needles.ДЇor millions of years all humans, early and modern alike, had to find their own food. ScientistsВ sometimes use the term вЂњanatomically modern Homo sapiensвЂќ to refer to members of our own species who lived during prehistoric times. Modern human faces also show much less (if any) of the heavy brow ridges and prognathism of other early humans.В Our jaws are also less heavily developed, with smaller teeth. Housing this big brain involved the reorganization of the skull into what is thought of as 'modern' - a thin-walled, high vaulted skull with a flat and near vertical forehead. Modern humans have very large brains, which vary in size from population to population and between males and females, but the average size is approximately 1300 cubic centimeters. Like other early humans that were living at this time, they gathered and hunted food, and evolved behaviors that helped them respond to the challenges of survival in unstable environments.ДЄnatomically, modern humans can generally be characterized by the lighter build of their skeletons compared to earlier humans. During a time of dramatic climate change 300,000 years ago, Homo sapiens evolved in Africa. The species that you and all other living human beings on this planet belong to is Homo sapiens.
