Farmers Spread Celtic Language into Britain 6,000 Years Ago

A Reuters article reports that geneticist Peter Forster of the University of Cambridge has produced a study indicating that farmers carried the Celtic language through the British Isles, Ireland, and France over 6,000 ago. The study, published this week in the Proceedings of the National Academy of Sciences, is based on a concept known as mutational analysis -- the theory that that random mutations or changes in DNA average out to a steady rate -- to Celtic, one of the Indo-European languages. "We look at it like we do at DNA, said Forster, "as a string of information."
