ok.

the sort of wet blanket moment is in realizing that a lot of the existing native genome comes post-contact.

i believe that the modern siberian population that natives are related to would have been living south of the glaciers at this time.

but the gene flow is complex.

they need to date the components, rather than rely on proportional analysis. that's not enough to understand anything.

my migration hypothesis had northern ("european") and southern ("asian") populations merging before the glacier cross. this just makes basic sense. any post-racial analysis would see that it just makes sense. the study basically confirms that.

but we know the admixture is large because the r1 mutation that is prevalent in eastern indigenous populations is relatively recent.

so, we need to date this carefully on a case by case basis. some will be ancient, some will be recent.

messy project, good luck.

nature doesn't get it, either.

*sigh*.

they were so close....making so many positive steps towards a greater understanding...

....and, then hierarchical racial systemics reared itself, again. natives and europeans mixing in canada would upset the racial purity dipshits. those dipshits are mainstream, though. of all races. so, to prevent the mixing they explain all the variation by an early split.

despite the reality that the evidence of late mutation is overwhelming.

this will sort itself out eventually. for right now, we can see that the field is still dominated by the mindset that wants to separate people into types.

very unscientifically.

and, no, it doesn't really explain why X ended up flung out in two different places. it reminds us of one already existing hypothesis, but it provides no further evidence for it.

again, they'd have to date it. i don't see any reason to think the barbary/pirate explanation is worse than the hybrid explanation. which was mine, btw. again.

nor is the idea of a greek or phoenician exploration at all outlandish. i mean, the guy presents it like it's crazy talk. well, why is X centered around the mediterranean, then, and nowhere else? seems to require a greater explanation, if you ask me.

turkish pirates, probably. there were a lot of them up and down the coast, you know.
