Was this ancient person from China the offspring of modern humans and Neandertals?

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.
