Found mysterious human ancestor

Найден таинственный предок человекаThe researchers first used a combination of algorithms and deep machine learning and statistical methods to study human evolution.

Scientists from the Institute of evolutionary biology, National research center genetics Center genomic regulation and the Institute for genomics, University of Tartu with the help of artificial intelligence found in the genome of Asians traces of a previously unknown hominid.

About the discovery reported on the website of the Center for genomic regulation.

The “deep learning” is an algorithm that mimics the nervous system of mammals with different artificial neurons, – said project Manager Oscar Lao. We used this property to obtain an algorithm for learning to predict the demographics of the person using the genomes obtained by hundreds of thousands of simulations. Whenever we run the simulation, you are traveling on a possible path in the history of mankind.”

Modern analysis of human DNA suggests that Neanderthals and denisovans interbred with people from Africa and
Asia more than 40 thousand years ago. The use of neural networks allowed us to detect traces of a third human ancestor. Until now, its existence was only a theory.

The researchers suggest that an unknown human ancestor was a descendant of the Neanderthals and the denisovans. By the way, the insights of artificial intelligence are confirmed by the analysis of fossilized remains found in Denisova cave in the Altai.
