According to recent studies, our human ancestors lived scattered across Africa. This means that they covered different habitats and their lifestyle was influenced by environmental conditions. This means that they might have migrated, but they didn’t consider forests and dessert proper living areas.
The findings were made by a team of scientists led by Dr. Eleanor Scerri, a professional working at the Max Planck Institute for the Science of Human History and Postdoctoral Fellow at the University of Oxford. After doing all calculations and imagining a different scenario, researchers found that the diversity of human forms comes from millennia of separation. In fact, our present species has been shaped by these factors.
A species gave birth to many origins
So far, we were sure that our species was born in Africa, but how we evolved throughout the continent remained a subject for research. Many experts believed that, at the beginning, there was only one ancestral population and its members exchanged genes and technologies between them. They used similar stone tools and other types of accessories, so they might have discovered them together.
A paper published this week in Trends in Ecology and Evolution argues this view in a certain way. Several types of studies – anthropological, archaeological, researches conducted on genes and other new and more detailed reconstructions have revealed the fact that the present human species have been shaped by Africa’s climates and habitats. The process lasted over 300,000 years.
These arguments are supported by human fossils as well. By looking at the morphology of human bones and the way it evolved in the past 300,000 years, we notice a combination of modern and ancient features which led to the present anatomy. Scientists say that this information is useful in finding out why the present human population is divided into so many subspecies and races.
