Ancient astronaut theorists take note as scientists trace ancestral home of all humans to southern Africa

According to researchers, all modern human beings could have descended from people now in Botswana.

Scientists believe they have discovered for the first time the “cradle of humanity,” where the first modern human beings evolved before spreading throughout the world.

In the prehistoric wetland of Makgadikgadi – Okavango just to the south of the Zambezi River are believed to have flourished.

Researchers have shown that the genetic root of every modern person comes from this region 200,000 years ago, a study of DNA records and migration patterns shows.

The wetland was a warm, lush green Garden of Eden in which early humans thrived before migrating when a wobble in the earth’s axis 130,000 years ago caused the climate to turn dry.  

And direct descendants of these pioneers can still be found living in the arid Kalahari desert today.

‘It has been clear for some time anatomically modern humans appeared in Africa roughly 200,000 years ago,’ said the lead researcher, Professor Vanessa Hayes.

‘What has been long debated is the exact location of this emergence and subsequent dispersal of our earliest ancestors.’

Professor Hayes, from Sydney University, studied the DNA of more than 1,200 living African people to pinpoint the origin of modern humanity.

She took samples from people called the Kehoe San, who live in rural Africa and who are known to be the most closely related to the original humans, and people genetically linked to them.

Her team could trace common ancestors of all the distinct groups back to the Makgadikgadi area of Botswana, which they have deemed the origin of man.

The findings, published in the journal Nature, add to existing geological and fossil evidence that proves Lake Makgadikgadi was home to early humans. In the past, scientists have suggested that smaller pockets of humans evolved in various places around Africa before spreading.

But Professor Hayes said the original humans evolved in the Makgadikgadi–Okavango wetland and remained there for a whopping 70,000 years.

‘There was a very large lake,’ she said. ‘By the time modern humans arrived, it was breaking up into smaller ones – creating a wetland.’

And she claims ‘green corridors’ of vegetation grew out of the wetland, which developed from a lake twice the size of the 23,000-square-mile Lake Victoria in Tanzania and Uganda, allowing people to migrate north-east and south-west.

Wetland is one of the healthiest ecosystems for sustaining life and would have been abundant enough for the human species to become established.

The climate then changed, drying out the land and causing the wetland to become what is now a region of salt pans and desert – this forced people to migrate.

Professor Hayes said: ‘The first migrants ventured northeast, followed by a second wave of migrants who traveled southwest.

‘A third population remained in the homeland until today. ‘In contrast to the northeasterly migrants, the southwesterly explorers appear to flourish, experiencing steady population growth.’
