Chinese paleoanthropologists have discovered that people living on the Qinghai-Tibet Plateau for the past 5,000 years share a single origin derived from a northeast Asian group that mixed with a separate, unknown group.
"The arrival of this variant must have occurred sometime prior to 5,100 years ago in an ancestral population that contributed to all plateau populations," said Fu.Northeastern populations younger than 4,700 years ago saw an influx of additional northern East Asian ancestry in lower elevation regions, according to the study.
