"Culture at least implies a breeding group" - I'd say that really is a fine example of bollocks (since this is the word which defines this thread).

Genetically I am 100 per cent Irish, which means I've probably got Danes, English, Scots and the occasional German among them, and quite likely the occasional black slave.

I've got cousins in Ireland, England, America, Australia, New Zealand, Argentina and various parts of continental Europe, and probably elsewhere.

The breeding group we belong to is Homo Sapiens.
