Homo Sapiens are believed to be evolved in Africa some 200,000 years ago due to a dramatic climate change. Their behaviors had some evolution over the years and made them face the challenges successfully in an unstable environment. In comparison to the early humans, these modern humans had the possession of a skeleton that was lighter in build. These modern humans were also having larger heads with short femoral necks attached to them. Their brain size was around 1200 cc which was much larger in size.
