Could Iran's plateau be the first home of humans?
Iran's plateau could be the place where humans first settled after leaving Africa. This place was like a 'hub' for the hub population, from where they spread throughout Asia and Europe.
Some such characteristics have been found in the dna of the people of iran which are similar to the first humans to come out of Africa. The study of the old climate shows that the plateau of iran was good for humans to live at that time.
How did the scientists do the research?
Scientists have used the dna of two ancient humans: Tianyuan and Kostenki. Tianyuan was a 40 thousand year old person who lived in east Asia. Kostenki was a 38 thousand year old person who lived in western Russia. Scientists saw how similar the dna of different groups is to the dna of Tianyuan and Kostenki. Based on this similarity, they created a map in which every group is shown by a point.
This map has two axes - one for Tianyuan and one for Kostenki. The point where these two axes meet represents the 'hub population' when the EEC (East Eurasian Core) broke away from it. A little further from this meeting point, there is another point on the blue axis that represents the hub population as it changed after the EEC broke away from it.
