Basically like the hillbillies of North America?? Incest when it is done in America, Nation building when the UK does the same thing. Do you know how many ways that is a stupid way to get along in a global environment???A DNA study of Britons has shown that, genetically, there is not a unique Celtic group of people in the UK.
According to the data, those of "Celtic" ancestry in Scotland and Cornwall are more similar to the English than they are to other Celtic groups.
The Scots, Welsh and Irish being "Celtic" is nothing more than a myth invented by 18th Century Scottish, Welsh and Irish nationalists and there is no evidence to suggest they are in any way related to the true Celts of mainland Europe
The fact is that the vast majority of Britons share the same lineage. Around 80% of people living in the British Isles are descended from the indigenous European Palaeolithic hunter gatherer population.
