The sentences above are special. According to newly published research, they comprise words that have been passed down for millenia, from a language that all but disappeared toward the end of the last ice age. What remains of that tongue are words like the ones above – words that mean the same thing today, and sound almost exactly the same, as they did 15,000 years ago.

The Washington Post's David Brown has the details on the study:

A team of researchers has come up with a list of two dozen “ultraconserved words” that have survived 150 centuries. It includes some predictable entries: “mother,” “not,” “what,” “to hear” and “man.” It also contains surprises: “to flow,” “ashes” and “worm.”

The existence of the long-lived words suggests there was a “proto-Eurasiatic” language that was the common ancestor to about 700 contemporary languages that are the native tongues of more than half the world’s people.

“We’ve never heard this language, and it’s not written down anywhere,” said Mark Pagel, an evolutionary theorist at the University of Reading in England who headed the study published Monday in the Proceedings of the National Academy of Sciences. “But this ancestral language was spoken and heard. People sitting around campfires used it to talk to each other.”


The 23 "ultraconserved" words are as follows, listed beside the number of language families in which they have cognates (i.e. words that sound and mean the same thing in different languages):

7 - thou
6 - I
5 - not, that, we, to give, who
4 - this, what, man/male, ye, old, mother, to hear, hand, fire ,to pull, black, to flow, bark, ashes, to spit, worm
