How ancient, recurring climate changes may have shaped human evolution
Shifting habitats implicate a disputed ancestor in the rise of Homo sapiens and Neandertals
The climate change–induced travels of a disputed hominid species called Homo heidelbergensis, represented here by a roughly 600,000-year-old East African skull, led to the evolution of H. sapiens in southern Africa and Neandertals in Europe, a new study claims.
