New David Reich study links early human expansion to Neanderthal origins

A new study by Harvard geneticist David Reich proposes that an early range expansion of modern humans around 300,000 years ago may have played a key role in the origins of Neanderthals. Using spatial population models, the research suggests a way Neanderthals could have retained mostly archaic ancestry while carrying modern-human mitochondrial DNA, offering a new explanation for their genetic makeup.

Why now: Fresh research from a prominent ancient-DNA researcher challenges assumptions about how Neanderthals emerged.
