Scientists have sequenced the first ancient human genomes from Ireland – shedding light on the genesis of Celtic populations.

A genome is the instruction booklet for building and maintaining a human – comprising three billion DNA letters.

The work shows that early Irish farmers were similar to southern Europeans.

Genetic patterns then changed dramatically in the Bronze Age – as newcomers from the eastern periphery of Europe settled in the Atlantic region.

Details of the work, by geneticists from Trinity College Dublin and archaeologists from Queen’s University Belfast are published in the journal PNAS.
