After having a tryst from a modern individual and a Denisovan, a child was conceived, who left descendants, a number of who became Tibetans

Yet Tibetans, whoever ancestors have resided in the plateau for at the least 30,000 years, are well-adapted to the environment that is low-oxygen many thanks in component to specific versions associated with the genes EGLN1 and EPAS1, that are taking part in sensing and adjusting to oxygen levels. The anthropologist Cynthia Beall and colleagues showed that Tibetans can trace their ancestry to two previously distinct populations, related to modern Han Chinese and Sherpa in a paper published, the geneticist Anna Di Rienzo. By examining the genomes of most three living populations – Tibetans, Han Chinese and Sherpa – the researchers pieced together a sequence of events by which individuals from the lowlands associated with the modern Han Chinese migrated to higher altitudes, where they blended with those already present (loved ones of the Sherpa). The useful EGLN1 and EPAS1 gene versions were thought to currently be there in the relatives associated with the Sherpa, and acquiring these gene versions aided the newcomers to survive and pass their genes on.
