Humanity’s previously unknown “ghost” ancestor discovered

Anatomically, the modern human species that we know today, They appeared on the African continent 300,000 years ago. It evolved from Homo heidelbergensis or a similar species, and humans who migrated from Africa gradually replaced or interbred with local archaic human populations.

The remains of a young girl who lived right during this crossing shocked scientists. After the discovery, scientists has partially proved a theory that has been around for a long time, thanks to deep learning algorithms that examine the ancient and modern human genetic code.

ANCIENT HUMAN FOUND NEVER BEFORE DISCOVERED

These remains It belonged to a young girl over 50,000 years ago and appeared to be a “hybrid” ancestor of modern humans that scientists had never encountered before. Scientists have also found evidence that the person to whom these remains belonged was not alone.

The details entered in the Webtekno news from In the study, which began in 2019, scientists, with the help of an artificial intelligence, studied the species modern humans mixed with during the great migration from Africa to Eurasia. Thanks to artificial intelligence that compares the genes in the relics with the genes of modern humans. It turned out that the person to whom the 50,000-year-old remains belonged was an intermediate human ancestor who emerged during this interbreeding.

Until now, Neanderthals and Denisovans were thought to be the related species in this migration. However, in this study, a third ancient species was revealed to have lived in Eurasian DNA long ago, thanks to deep learning algorithms.

Using a statistical technique called Bayesian inference, the researchers found evidence for what they call “backbreeding,” in other words, a “ghost” archaic population into which modern humans interbred during African migration.

But according to the scientists, the work has only just begun. Applying this type of AI analysis is a new technique in the field of human ancestry, and the known fossil evidence we are dealing with may be extremely scarce. On the other hand, according to the research, what the team found not only explains a long-forgotten process of introversion but also provides insight into who we are today.
