>>11662969>>11662973Sorry, this just got to me because, let me guess. You just took the sentence you like?
It's called a Theory because it can be proven by tracing mithochondrial DNA between haplogroups, Autosomal DNAs, and even the Pathogenic DNA that has left its marks from parent to offspring 70–90% of humans have polyomavirus
We could even trace migration patterns of various groups based on the stone tools they have left, the signs of agriculture and collapse of their tribes, and the new migration routes they traveled through. Some groups returned to Africa.
Theories cannot be disproven, only improved. Haplogroups that did not descent from African haplogroups are not unique at all. There's Haplogroup C for Asian and Oceanic people for example.
And no, it does not really mean that it didn't came from Africa, rather it just mean that the gene was isolated for so long it developed unique traits that made it different from its parent
