A new study claims that the ancestors of the modern man may have emerged from Botswana territory south of the Zambezi River in Africa and spread to other regions. Here are the details…
It is estimated that the people living here for 70.000 years are scattered in other parts of Africa through green corridors formed by climate change and the change of rain. Some of these people migrated from Africa to other continents 130,000 to 110,000 years ago. “It has been known for some time that modern human was seen in Africa 200,000 years ago. Professor Vanessa Hayes, a geneticist from Garvan Medical Research Institute in Australia. The debate about this emergence and the point where our first ancestors began to spread around the world has been going on for a long time.”
According to the research published in Nature magazine, the ancestors of modern people living in this region for 70.000 years migrated to the northeast in the first wave of immigration and to the southwest in the second wave, and a third of the population remained in the same area. Using geological and climate simulations with genetic data, the researchers tried to reveal what environment Africa was 200,000 years ago.
‘The evolution of modern human is a complicated process. However, some of the experts are skeptical about the results that Hayes has received from 1217 people living in the South African region and passed from mother to child on the samples of mitochondrial DNA.
Professor Chris Stringer from the Natural History Museum in London says that the evolution of Homo sapiens involves a complex process and that the origin of humans cannot be determined by mitochondrial DNA alone. “Like many other studies focused on only a small part of the human genome, a single region, a uniform stone tool, or a single” critical “fossil, it is not possible to reveal our mosaic origin here,” says Stringer.
Stringer also says that when the Y chromosomes passing through the father are examined, data are found by the father that our ancestors are based on west Africa, and when the human genome is considered as a whole, the first people migrated from the east of Africa. “This and similar data actually show that our origin is a composition based on our ancestors from different parts of Africa, and it is also a mixed race with groups of people outside the continent,” he says.
In other studies based on fossils, the home of modern man was identified as East Africa. There are also theories that the evolution of humans occurs simultaneously at various points in the African continent and may have spread from more than one region.
