An AI Found an Unknown 'Ghost' Ancestor in The Human Genome

She was a teenage girl from over 50,000 years ago who looked like a descendant of modern humans that scientists hadn't seen before.

Researchers have found that she wasn't the only one. In a study analyzing the tangled mess of humanity's prehistory, scientists used artificial intelligence to identify an unknown human ancestor species that modern humans encountered and shared dalliances with.

"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

Modern humans forged some other things as well as breeding with ancient and extinct hominids.

Neanderthals and Denisovans were thought to be part of these occasional sexual partners until 2010.

A third ex from a long time ago was isolated from the rest of the population thanks to deep learning.

The researchers found evidence that modern humans interbred with an archaic population during the African exodus.

It's possible that this third population in humanity's sexual history was a mix of Neanderthals and Denisovas, according to the researchers.

There's still more work to be done, but from the perspective of deep learning, it's a hypothetical corroboration of sorts of the teenage girl.

"Our theory coincides with the hybrid specimen discovered recently in Denisova, although as yet we can't rule out other possibilities," one of the team said in a press statement.

There are a lot of discoveries being made in this area of science.

A team of researchers identified evidence of a third interbreeding event with Denisovans and Neanderthals, as well as a pair of papers that traced the history of interbreeding between those extinct species.

There is more research to be done. It's a new technique in the field of human ancestry and the fossil evidence we're dealing with is very little.

According to the research, it's a dalliance that informs part of who we are today.

"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 if these explain the whole picture," he said.

There is still something in the genome that is very different from the other parts.

The results were published in a journal.
