“Million-year-old” fossil skulls from China are far older—and not Denisovans

Two skulls from Yunxian, in northern China, aren’t ancestors of Denisovans after all; they’re actually the oldest known Homo erectus fossils in eastern Asia.

A recent study has re-dated the skulls to about 1.77 million years old, which makes them the oldest hominin remains found so far in East Asia. Their age means that Homo erectus (an extinct common ancestor of our species, Neanderthals, and Denisovans) must have spread across the continent much earlier and much faster than we’d previously given them credit for.

Yunxian is an important—and occasionally contentious—archaeological site on the banks of central China’s Han River. Along with hundreds of stone tools and animal bones, the layers of river sediment have yielded three nearly complete hominin ...
