The girl's bone found on Siberia revealed the peculiarities of mating in our ancestors



As the Independent writes, there were two very different groups of people who lived in Eurasia about 50,000 years ago and were devoted to thousands of evolutionary years – Neanderthals and Denizovists (Denisov people).

An analysis of the bone fragments detected in the Siberian cave now shows that this is a bone of a girl whose mother was a Neanderthal, and her father, Denisov's husband.

Scientists have tried to isolate the complex relationships between our ancestors slowly, using the very old DNA. These efforts led to the conclusion that few who had chosen their partners had a kind of superstition or attitude.

"However, I had never thought that we would succeed and discover the true offspring of the two groups," says Dr. Viviane Slon, one of the authors of the Max Planck Institute for Evolutionary Anthropology and Discovery.

The Denisov cave, which until now was the only physical evidence of the existence of the mysterious Denisov people, turned out to be a treasure trove of the development history of human history. The bone fragment "Denisova 11", based on the new study, was discovered in 2012 by Russian archaeologists and then sent to Germany for genetic analysis.

An essential new discovery message, highlighted in the journal Nature, is that the mixing of species was not only general, but also a common phenomenon.

"A specific cross was found, the result of such a pairing found in a small fossil, clearly indicates that such a pairing was not rare, at least when both kinds of people met each other under all circumstances," said Chris Hooger, professor of natural history. in the investigation.

The genomic analysis also showed that the girl who at the time of her death, a Denisovite, was 13 years old, had at least one ancestor of the Neanderthal in the family tree. It shows different types of mixing cases in one family.

"Neanderthals and the people of Denisov did not have much opportunity to meet, but when they met, they often murmured – much more often than they used to," says Professor Svante Paab, a pioneer in the study of prehistoric DNA in DNA, and also participated in the new study.

Professor Mark Thomas, a specialist in evolutionary genetics at the University of London, explained that the evidence of mixing of ancient human species can still be found in today's human DNA. Today it is believed that about five percent of some people in the DNA, especially from Papua New Guinea, descend from the people of Denisov.

In recent years there has been evidence of a large number of people and the combination of the Neanderthals, including the specimen of a modern man found in Romania, an ancestor of the Neanderthal four years ago.

Although the Neanderthals and the Denisovites were sufficiently equal to have a common offspring, the generations of these old people differed significantly more genetically than any other group.

"They were clearly not racists – this is the lesson of our distant ancestors," says Thomas Thomas.
