Humans originate in Africa

Scientists have long affirmed that humans originated in Africa. Until recently, a new DNA study showed that the "Eden Garden" - the site of the first human inhabitants - is located in southern Africa, near today's Namibia border.

It is the land of the San people with the main form of hunting for thousands of years. Scientists believe that this is the oldest human race on earth. They were the next generation of human ancestors, from which all African tribes formed and later left the black continent living on the planet. The study results show that San people have the most diverse genotypes in Africa. In addition, nearly three-quarters of African-Americans could find their ancestors in West Africa.

This is the result published after a decade of research led by female professor Sarah Tishkoff, a working geneticist at the University of Pennsylvania. She traveled to remote and dangerous lands on the black continent and a group of researchers from many other countries, aiming to sample DNA from more than 3,000 modern African residents from 121 population areas. different.

The results showed that all DNA sampled residents originated from only 14 different ancestral ethnic groups, and the languages ​​they spoke were similar to the genetic variants. Researchers also point out that a small group of about 150 Africans went 'sowing' around the world, shortly after crossing Hong Hai.
