Alan, are you trying to say that the potato gave people in Ireland a
But it wouldn't have much to do with the distribution in parts of Europe
that did not adopt the potato at that time.
What is more, you'd have to demonstrate that particular haplogroups in
Ireland were more likely to adopt the potato than others and that this
influenced the distribution of haplogroups in Ireland today.
