A recent study of the genomes of the two most famous types of ancient humans – Neanderthals and denisovans – discovered new previously unknown ancestor of modern man.
There is a possibility that this unidentified ancestor in fact belonged to Homo erectus, which is believed to have been extinct for over 100 thousand years ago. But since there are not found any DNA of Homo erectus, sure to be impossible.
In this study, scientists from cold spring Harbor (USA) used a Bayesian algorithm ARGweaver-D to explore patterns within the genomes – in this case, the DNA of two Neanderthals, Denisova and one of two modern Africans. The resulting model can match the facts of the mixing of DNA with specific historical time periods. At the end of its work it turned out that about 1% of the DNA of the ancient denisovans has the unknown origin.
Approximately 15% of detected “superdrink” regions of DNA that were found in the genome of the denisovans, is still present in the genome of modern humans. What happened to the lost kind, from whom we received them, remains to be seen.
