The ancestors of people from across Europe and Asia may have spoken a common language about 15,000 years ago, new research suggests.

Now, researchers have reconstructed words, such as ‘mother,’ ‘to pull’ and ‘man,’ which would have been spoken by ancient hunter-gatherers, possibly in an area such as the Caucusus. The word list, detailed today (May 6) in the journal Proceedings of the National Academy of Sciences, could help researchers retrace the history of ancient migrations and contacts between prehistoric cultures.

‘We can trace echoes of language back 15,000 years to a time that corresponds to about the end of the last ice age,’ said study co-author Mark Pagel, an evolutionary biologist at the University of Reading in the United Kingdom.

But not all linguists believe in a single common origin of language, and trying to reconstruct that language seemed impossible. Most researchers thought they could only trace a language’s roots back 3,000 to 4,000 years. (Even […]
