Taking a comparative look at Paul's GD distances between Irish & Scottish samples and considering Bernard's remarks could we be looking at the result of migration into Scotland to avoid being wiped out on the home turf that Bernard is suggesting? Based on my looks with in the project I've been looking at, I have a couple of groups that likely do not fit that scenario as the GD between them and the rest is excessive to 4000 years worth which could suggest a couple of other things; however, in regard to Paul's Byrnes, it very well could suggest a migration for reasons of safety...speculatively, and there by because they did survive to continue to reproduce they would evidence an older lineage.
