If you share DNA with one of the three Bronze Age men from Rathlin Island and with an earlier Ballynahatty Neolithic woman, then you’re Irish and Celtic.
Analysis of the remains of a 5,200-year-old Irish farmer (the Ballynahatty Neolithic woman) suggested that the population of Ireland at that time was closely genetically related to the modern-day populations of southern Europe, especially Spain and Sardinia. Her ancestors, however, originally migrated from the Middle East, the cradle of agriculture.
The Rathlin Island men share a closer genetic affinity with modern Irish, Scottish, and Welsh populations than they do with earlier Neolithic remains, such as the Ballynahatty woman. This suggests a significant genetic shift and the establishment of a distinct population in Ireland during the Bronze Age.
Haemochromatosis Mutation:
One of the Rathlin Island men carried the common Irish haemochromatosis mutation. This genetic variant, which causes the body to absorb too much iron, is very common in Ireland and was also found in the Rathlin man. This indicates that the mutation was established in the Irish gene pool by the Bronze Age.
Thanks! The distinct shift during the Bronze Age was the arrival of the Celts. It’s not surprising that some of the earlier people’s genome has survived thanks to intermarriage.
