Whatever happened to Y chromosome haplotype IJ? Were they Atlantean?

Question

It's thought to have existed in the middle east, and been the father of haplotypes I and J, but they've never found a trace of it. It had to have been fairly common to have produced so two such widespread 'sons', so where did it go? There are no notable disasters in the middle East known to account for it, as far as I know.It's too late for Toba to kill it off. Also, one of the 'sons', J has lots of uncommon in numbers but has lots of different types, which is very suspicious.

Were they 'Atlanteans?' Wiped out by a plague, sailors?

What could account for such a bizarre spread?

Does anyone have a good site for lists of the respective ages of Y DNA types?

It's like Sudoku with bloodlines.

See Ed, no Britney. The devil made me do it.

Answer 1

I've long wondered if IJ was a Neandertal hybrid, but have found zero real evidence to support that. Looking at the distribution of this group's offspring, I can make a weak case for that, but due to lack of evidence have not done so.

Chuckle, you've forced me to make public a budding hypothesis with very sparse supporting evidence. I hear Britney is a creationist?

Edit:

While IJ "appears" to have come from "Adam" we are filling in a large gap from F with conjecture there. To my knowledge, we have found "no" IJ DNA & the haplogroup is only "assumed" to have existed because the jump from F to J & I is too large to designate F as the founding Haplogroup for either Haplogroup. I have a sneaking suspicion that "IJ" is a derived haplogroup to shore up the Afrocentric Hypothesis... but can't find anything proving that.  OK, you made me say it!

As for Atlantis, you must 1st prove this place existed then develop an explaination of what happened to the ones not killed in the disaster, if you are to develop a credible hypothesis.  However, that is not much worse than inventing an entire haplogroup to make the OOA hypothesis work.

Answer 2

OOA, Out of Atlantis
