Recently, U.S. experts found traces of hybridization with “ghost man” (unknown ancient species) in the genome of West Africans. The study was published in the journal Science Advances. It has been reported that recent studies have shown that ancient humans had interbred with Neanderthals and Denisovans of similar ethnozoic species. There is a significant proportion of Neanderthal genes in the Genomes of Eurasians, while the Genes of denisova sit in the genomes of residents of Australia and Oceania.
It was previously thought that hybridization occurred after people left Africa, so that indigenous Africans did not have genes that were planted by others. And new research suggests that although modern West Africans did not have Neanderthals or Denisovans, in the past, West Africans may have interbred an unknown ancient species, known as “ghost sapites.”
Ucladur Durvasula and Sriram Shankaralaman, geneticists at the University of California, Los Angeles, studied 405 genomes of West Africans and compared them to those of Neanderthals and Denisovans.
Because ancient human remains in West Africa are rarely found and are in poor condition, DNA cannot be extracted and can only be expected in computer modeling.
However, the results suggest that while computer modeling may help to detect the effects of an unknown species on the genomes of modern Africans, there is still insufficient research into genetic variation in modern Africans.
