New Study Reveals Our Ancestors Crossed Mysterious Race

A new study is shaking the history of our ancestors. According to research published in Cell magazine in February, Homo sapiens would have bred with different populations of the now defunct Denisova Hominid.

The proof is that the DNA of these human-like primates has been found in the genomes of some people today. The researchers extracted samples of Denisovan body remains found in a Siberian cave, revealing the ancient cross between species.

What scientists have known so far is that Homo sapiens had sex only with Neanderthal Man, as the genes of this species make up up to 4% of the genes of humans from around the world, including the United Kingdom, Japan, and Japan. United States.

Shared Genes

The new study shows that the crossing with the Denisova hominid was relegated only to Siberia. More than 5, 500 genomes of modern humans from Europe, Asia and Oceania have been examined for a single DNA that shows signs of crossbreeding. They then extracted the DNA and compared it with those of the Denisovans and Neanderthals.

The results showed that the genomes contained a dense group of DNA that approached the Neanderthals. Some, especially from East Asians, had groups that matched Denisovans.

But the most interesting result was that some people's DNA did not match that of the Neanderthals: they only partially resembled that of Denisovans. This was the definitive proof of crossbreeding. The authors assume that as humans migrated eastward, they encountered different populations of the Denisova hominid.

One of the variations was found in inhabitants of China, Japan, and Vietnam. The other appears somewhere in Southeast Asia. "It could have been on an island on its way to Papua New Guinea, but we don't know clearly, " said Sharon Browning, lead author of the study.

Moreover, these findings indicate that there are additional mixtures and instances of intersections, given the variety of groups that existed. Researchers are already planning to investigate these relationships, which may further reveal the complexities of our human past.
