And then…there was one. One member of the Homo genus left. And it was us-Homo sapiens.
One of the more interesting things about us is our extreme variety. Modern human skulls can be divided into five geographic groups (the Caucasoids of Europe, North Africa, and western Asia; the Mongoloids of eastern Asia and North and South America; the Blacks of sub-Saharan Africa; the !Kung San and Khoikhoi from the Kalahari Desert and the Cape of Africa, and the Australoids of Australia, Tasmania, and New Guinea). We also demonstrate remarkable variability in the skeleton, which are linked to the demands of the environmental regions with which the skeletons are associated. But these cut-and-dry lines between the different geographic groups has been blurring since the end of the last Ice Age, when the trend of seperate human populations began to reverse.
We appeared about 200,000 years ago in Africa.
