Irish language origins: New DNA study traces Celtic roots to central Europe

The Anglo-Celtic or modern Celtic languages include Irish, Scottish Gaelic and the Manx language, while Welsh, Breton and Cornish form a second branch.

It is at Ireland's edge that Gaeilge is still commonly spoken, but centuries ago, Celtic languages like it most likely belonged to a people at the heart of Europe.

This is what a new research paper published in the science journal Nature suggests, based on an analysis of the ancient DNA of more than 4,500 people.
