Spreading Out Of Hominins
Part of the study was that these first humans were strategic enough to make their tools during their time at about 2.5 million years ago. This tool advancement might have helped them survive their time. They might have learned to create tools for hunting, cooking, and even for making their homes. They had complex environments back then, which made them think of survival ways. The change in climate by about 2 million years ago might as well affected them greatly, especially the spreading out of hominins all over Africa.
Homo Erectus
Homo erectus was discovered to have led their way out of the constraints of Africa. Some of the fossils were later located to be in East Africa. Those found were studied and calculated to be two thousand years old. After a couple of hundred thousand years, it could also be found in what is now known as the far easter European country of Georgia. It later spread and found its way into Asia. Some species flourished living in Java, an island in Indonesia, evidently, for more than a million years.
