is there some sort of cutoff point where scientists decided “everyone in Ireland 100,000 years ago will be considered 100% Irish”?
In: 12
The difference genetically between an Irish, Japanes or African human is very very small. Vast majority of the genes are the same.
What you are really asking or should be asking is when did the gene that is associated with those cultural groups develop and how does that make us different?
We place a lot of emphasis on looks and this can be a great bias in our thinking.
