AI in paleoanthropology: Hybrid ancestor to modern humans

Paleoanthropologists and anthropologists are using artificial intelligence to reconstruct the complicated patterns of interbreeding among ancient tribes that led to the modern human species.

Recently, scientists discovered evidence of a highly distinct adolescent girl over 50,000 years old and had remarkable peculiarity as a ‘hybrid’ progenitor to contemporary humans that scientists had never seen before, and strangely, she was not alone.

 In a 2019 research, scientists use artificial intelligence (AI) to locate an unknown human ancestor species that modern humans encountered – and enjoyed dalliances with – on the long trek out of Africa millennia ago to understand the complex mess of humanity’s prehistory.

The exodus out of Africa occurred some 80,000 years ago, when a portion of the human population, which formerly included all of today’s people, left the African continent and went to various mainland’s, resulting in all of today’s population.

As modern humans carved their way into Eurasia’s continent, they fashioned several unique products, such as rearing the elderly and terminating primates from various species. These were the Neanderthals and Denisovans, ancient humans who interbred with the early moderns, leaving DNA fragments in non-African descendants’ genomes today.

However, because of profound learning calculations filtering through a complex mass of outdated and contemporary human genetic code, the third ex from some point in the past was isolated in Eurasian DNA in this study. The scientists uncovered confirmation of a “third introgression” – a “ghost” bygone population that current humans interbred with during the African mass exodus – using a scientific strategy known as Bayesian induction.

From a deep learning perspective, it’s speculative support for the high school young girl ‘hybrid fossil’ identified in 2018; even though there’s still more work to be done, and the examination projects themselves aren’t directly related. However, scientific revelations are coming thick and fast around here.

There is still a lot to uncover and work to be done in this area. It is a new way of using artificial intelligence in human genealogy, and there is a limited amount of fossil evidence that people can manage.

“We thought we’d attempt to discover these locations in the genome with huge changes, check which ones are Neanderthals and which ones are Denisovans, and then see whether they explain the complete picture,” Bertranpetit remarked.

He further added, “If that happens, even if the Neanderthal and Denisovan bits were removed, there is still something in the DNA that is quite distinct.”
