Human Ancestors From Africa

A scientific consortium has found evidence that as thought earlier our Human Ancestors did not come from a single large ancestral population from just one region of Africa. On the contrary they were scattered across Africa and separated by diverse habitats and environmental boundaries like the forest and the deserts. This separation for thousands of years paved way for staggering diversity of human forms, and the mixing of this diversity ultimately shaped the species that we are today.

To get an in-depth idea as to why the human populations were so subdivided, the researchers studied the past climatic conditions that prevailed and the changes in the environment that took place over the years. The inhospitable regions of Africa today like the Sahara were once lush green and wet with network of rivers and lakes and abundance of wild life. While some tropical regions that today are hot and humid, were once arid. These changing environments were forces that drove both the animal communities and many other sub-Saharan species to exhibit evolutionary relationships amongst the biological entities that survived during that time. During these environmental changes that took place the species living there at times went through many cycles of isolation, and these led to local adaptation and development of different unique cultural as well as biological makeup and genetic as well as cultural mixing. The research calls for a total rewriting of the human evolution from Africa.  New research and findings tells a new story, the ancient human population did not just emerge from the eastern Africa as previously thought.
