While scientists don’t know much about the recently spotted ancient human ancestor, the researchers know that it was a female that lived about 50,000 years ago. But she is unique for the human life evolution on the Earth, as she was a hybrid between ancient human species. An artificial intelligence system found a “ghost” in a human genome that led to the discovery of the “hybrid” in a Siberian cave.
“About 80,000 years ago, the so-called Out of Africa occurred, when part of the human population, which already consisted of modern humans, abandoned the African continent and migrated to other continents, giving rise to all the current populations,” said evolutionary biologist Jaume Bertranpetit from the Universitat Pompeu Fabra in Spain.
This recent finding proves the interbreeding between modern-day humans, Homo Sapiens, and ancient human ancestors, other than the Neanderthals and Denisovans. Now, the scientists believe that Homo Sapiens also bred with a third ancient human species, thanks to an artificial intelligence system that found a “ghost” in the human genome.

“This population is either related to the Neanderthal-Denisova clade or diverged early from the Denisova lineage,” stated the scientists in their study’s report. “Our theory coincides with the hybrid specimen discovered recently in Denisova, although as yet we cannot rule out other possibilities,” they added.
“There’s a lot more research to be done here yet. Applying this kind of AI analysis is a decidedly new technique in the field of human ancestry, and the known fossil evidence we’re dealing with is amazingly scant,” ScienceAlerts reported on the new study.
“We thought we’d try to find these places of high divergence in the genome, see which are Neanderthal and which are Denisovan, and then see whether these explain the whole picture. As it happens, if you subtract the Neanderthal and Denisovan parts, there is still something in the genome that is highly divergent,” added Jaume Bertranpetit.
