But Eve was still a half-robot living in Tanzania, right?

Stone Meadow: jbtilley: FTA: One possibility is that Perry's Y chromosome may have been inherited from an archaic human population that has since gone extinct. If that's the case, then some time within the last 195,000 years, anatomically modern humans interbred with an ancient African human.

Once you go black...

Hey, hey...the old memes are the best ones. ;^)

It does bring up the obvious question, tho. If Mr Perry's Y-chromosome is not modern human, what is it? It's not Neanderthal or TFA would have mentioned it. I wonder if it might have been H. erectus? After all they lived in SE Asia until about 20kya, so living in Africa until 340kya doesn't seem much of a stretch. Moreover, I have never heard of anyone isolating erectus chromosomes, so maybe this is one. Anyone know if the genome of the Hobbits has been worked out? Is there a tie-in?


Maybe they did, but.. "we now have a redating of Homo erectus soloensis from Java to about 150-550 thousand years ago"

JolobinSmokin: I've been wanting to do this for awhile now.

Being from Oklahoma my family history is very muddled and really only know the name of my great grand-father, but not his parents, the 1900 census said he didn't have any, so I could possibly be Native as we have always been told, but have no way of proving it.   My mother's side I do know more about we came to mainland america with the Spanish in the 1600's and the conquestadors, but this familial DNA is cheap enough.

Might do the Y for $339 this year and then do the mother side next year.

I might turn out to be a blah person.


$339? National Genographic used to be $120. Maybe it still is.

Yeah, I can't find a source for that now...maybe I was thinking of the Hobbits?
