South Africa: mankind’s ancestral home ‘traced in Botswana’

Scientists have called the region south of the Zambezi River the homeland of all living beings present on the planet.

The area is now dominated by saline waters, but in the past it was a large lake that was probably the home of all humans alive today, two million years ago.

According to researchers, our ancestors lived here for 70 thousand years, until the climate changed.

They started migrating here when the lush and fertile regions outside Africa came into existence.

However, one researcher has objected to this research published in the scientific journal Nature, saying that you cannot make the origin of a human story with only DNA knowledge.

according to researchers in humans are up to 70 thousand years and then moving to other parts of the planet due to changes in climate

“It is clear that physically modern humans existed in Africa two million years ago,” says Vanessa Hess, a professor of genetics at the Garvan Institute of Medical Research in Australia.

“The issue that has long been debated is that the exact location of human appearance and then our ancient ancestors have migrated to other parts of the earth.”

Professor Vanessa’s findings have attracted the doubts of other researchers.

The area that is being talked about here is in southern Botswana just south of Zambesi Tas.

Researchers suspect that our ancestors lived around the vast lake system in Africa. This lake area is now home to saline waters.

Professor Vanessa says, ‘This is a very wide area. At one time it would be very wet and lush. And it will certainly provide a fitting place for modern humans and wildlife to live. ‘

After 70,000 years, people started migrating here. Changes in rainfall patterns across the region led to three major displacements of 130,000 and 110 thousand years ago.

The first group of migrants moved to the northeast, the second group southwest and the third group remained there and is still settled today.

This estimate is based on information obtained from DNA tests of hundreds of African people in an attempt to identify the human family tree.

By combining genetics with geological and climate computer models, researchers were able to uncover the picture that the African continent was like two million years ago.

Restructuring the human story

However, one researcher has objected to this research published in the scientific journal Nature, saying that you cannot make the origin of a human story with only DNA knowledge.

Other analyzes have yielded different conclusions through fossil analyzes that point to East Africa as the primary habitat for humans.

Professor Chris Stringer of the Natural History Museum in London says that the evolution of the modern modern man was a complex process. Professor Stringer was not affiliated with the research described above.

Speaking to NP News, he said that you cannot know the only source of modern humans through scientific means because a small part of your research gene, which cannot tell the full story of human origins.

They say that the ancestors of modern humans may have more than one ancestral area that they did not even know.
