Yes, possibly! Trappist monks!
But I think just after the last ice age, which is what the Vedic stories are referring to, is about 20,000 years at least after HSS is supposed to have come out of Africa.
There's another gene study, I forget where I read it now, that follows HSS coming out of Africa somewhere around Ethiopia and crossing over into southern India. Some them stayed (thought to be today's Dravidians, Australoids etc, whose physiogony and language has some similarities with that of the Sumerians) and the rest carried on to Indonesia and all points east.
I guess languages can develop a lot in 20,000 years. ... but maybe not out of all recognition.
Sorry... rambling ... it's been a long day....
Here's a dumb blonde question - if we all came out of Africa, why is our skin not black? Skin pigmentation is due to genetics, so we wouldn't have gradually evolved fairer skins due to lack of sun rays on it ...well, not in such a short time anyway, imo.
