LIVE Techno – For scientist in Australia sparked debate after claiming it had found a home ancestors all modern humans.

Despite everything that science has revealed about the evolution and history of our planet over the years, there is still a lot we don’t know.

There always seems to be a new discovery that provides clues about our past, and in 2019, that discovery came in the form of mitochondrial DNA.

Quoted from the Unilad report, Professor Vanessa Hayes, a geneticist at the Garvan Institute of Medical Research in Sydney, and her team analyzed 1,217 samples of mitochondrial DNA, which is passed from mother to child.

The DNA comes from people who live in Africa the south, and Hayes notes that ‘we have known for a long time that modern humans originated in Africa and about 200,000 years ago’.

However, he noted that ‘what we didn’t know until this study was where humans actually came from.

Using this DNA, the team mapped the lineage of the oldest mother alive today and found that the line came from ‘home ancestor‘ spread from Namibia, Botswana and Zimbabwe.

Hoping to better pinpoint humans’ ancestral homes, the team then used geological, archaeological and fossil evidence to find out which areas might have made good homes.

Through this research, they discovered that there was once a body of water that was Africa’s largest lake system in the region, and that it split into vast wetlands around 200,000 years ago.

Hayes explained, “This place would be very fertile and would provide a suitable habitat for modern humans and wildlife to live.”

This lake, located south of the Zambezi river, may have sustained our ancestors for 70,000 years, according to research.

However, after the research was published in the journal Nature, other scientists doubted these findings. Says The Guardian, Chris Stringer, who studies human origins at the Natural History Museum in London, commented, “I’m very careful about using modern genetic distributions to infer exactly where population ancestors lived 200,000 years ago, specifically on such a continent. as big and complex as Africa.”

“Like many studies that concentrate on one small part of the genome, or one region, or one stone tool industry, or one ‘important’ fossil, this study cannot capture the full complexity of the origins of our mosaic, once other data are taken into account.”

“It is impossible to draw conclusions about the geographic origins of modern humans in Africa based solely on patterns of modern population variation. “This is because humans migrate long distances,” added Sarah Tishkoff, a geneticist at the University of Pennsylvania.

“They migrated out of Africa and around the world in the last 80,000 years and they have migrated across Africa in the past and in the past,” he added.
