Scientists have been pondering the question posed by the Neandertals—who were they, and what happened to them—since the first fossil remains were found in Germany's Neander Valley in 1856.
By combining what can be told by fossils and artifacts with what has been learned by geneticists, we're getting closer to answering those questions, said Richard Klein, a paleoanthropologist at Stanford University, California.
As little as a decade ago, the idea that humans and Neandertals interbred was considered a possibility. Today, genetic evidence indicates fairly conclusively that Neandertals were the immediate predecessors—but not ancestors—of modern humans.
