Our ancestors wiped them out tens of thousands of years ago. Were they able to call for help? New evidence indicates that perhaps they could.

Neanderthals, an archaic human species that dominated Europe until the arrival of modern humans some 45,000 years ago, possessed a critical gene known to underlie speech, according to DNA evidence retrieved from two individuals excavated from El Sidron, a cave in northern Spain.

The new evidence stems from analysis of a gene called FOXP2 which is associated with language. The human version of the gene differs at two critical points from the chimpanzee version, suggesting that these two changes have something to do with the fact that people can speak and chimps cannot.

The genes of Neanderthals seemed to have passed into oblivion when they vanished from their last refuges in Spain and Portugal some 30,000 years ago, almost certainly driven to extinction by modern humans. But recent work by Svante Paabo, a biologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has made it clear that some Neanderthal DNA can be extracted from fossils.

That is an exciting use of DNA to learn more about the past, including the development of the human species.

Of course, there is other evidence of Neanderthals being able to speak -- and type.
