Again, this was not an academic argument. I was asking about a thing that some everyday people believed. Like beliefs about good luck, or planting at the new moon. People making guesses about the world, which in fact is how science gets started.I don't know if this was a joke or not?
Anyway, no.
edit; I see quite a few people have already said as much.
There has been quite a lot of work done on genetics in the British Isles. Loads of books by scientists with loads of documentation to back up their findings. I've read a few of them - you have to be a little cautious of the aim of the author. Just because they are 'academics' does not mean their intentions are pure, nor is their research rigorous.
