If humans originated in Africa, how can we have anything other than 100% African DNA?

Question

is there some sort of cutoff point where scientists decided “everyone in Ireland 100,000 years ago will be considered 100% Irish”?

In: 12

Answer 1

Ancestry.com said My DNA was 65% from western Ireland; they even had it narrowed down to a small town near Galway. A year later, most of that moved up to Scotland, where the clan supposedly originated from before migrating there.

So I suppose I’ll move closer to Africa as the updates continue to come in. 😂
