DNAprint Genomics (DNAG)

[dgplexus]

Here's an example of just how messy and uncertain genetic inheritance analysis can be... In SE Asia, there are genes that turn up, that also turn up in Africa. "Out of Africa" proponents, of course, (of which I am not one,) assume those genetic elements stem from migrations out of Africa. But here's the problem... along all known and putative migration routes, there is a disjunction - those genes are not found along the routes, only in Africa and in SE Asia. I won't get into great detail here, but there are physical anthropologists who think a likely explanation is multiregional evolution, involving established regional populations that predate the "Out of Africa (2)" postulated event. Anyway, to put this into simple terms that apply to ancestry testing, the same or similar genetic elements could indicate African or SE Asian ancestry. And what happened to the population(s) (ancestral or otherwise) that connect those two population pockets? There is a lot of uncertainty. DNAPrint does a very competent job, in my opinion, in making sense of the data in an informative but not over-reaching way.
