Ancient ‘Tianyuan man’ is full-fledged Homo sapiens

|
DNA was analyzed from a partial skeleton of a 40,000-year-old human found at Tianyuan Cave.

When scientists excavated a 40,000-year-old skeleton in China in 2003, they thought they had discovered the offspring of a Neandertal and a modern human. But ancient DNA now reveals that the “Tianyuan Man” has only traces of Neandertal DNA and none detectable from another type of extinct human known as a Denisovan. Instead, he was a full-fledged member of our species, Homo sapiens, and a distant relative of people who today live in East Asia and South America. The work could help scientists retrace some of the earliest steps of human migration.

“The paper is very exciting because it is the first genome to fill a really big gap, both geographically and temporally, in East Asia,” says paleogeneticist Pontus Skoglund of Harvard Medical School in Boston, who was not involved in the work.

[T]he Tianyuan Man was not a direct ancestor, but rather a distant cousin, of a founding population in Asia that gave rise to present-day Asians, Fu’s team reports today in Current Biology. It also shows that these ancient “populations moved around a lot and intermixed,” says paleoanthropologist Erik Trinkaus of Washington University in St. Louis in Missouri, who is not a co-author.
