mtdna haplotype T

[wendland]

Does anyone know what is the significance of the mtdna haplotype T? There's a lot of talk about the Y chromosomes r1a and r1b and J, and others... I'm curious if anyone knows anything. Sykes who wrote the "7 daughters of Eve" said it was from a paleolithic population in Tuscany, and today is everywhere in Europe and the Near East, but especially Ireland. However the Genographic Project says that it is of highest frequency in the Urals, and that it is neolithic, and related to the spread of agriculture. I'd go with the Genographic just because it is newer and maybe more research has been done in the meantime. Does anyone know any more?

I think that the Tyrolean Ice Man was in T. Also, "Neolithic" and "Paleolithic" are not really good categories, because many haplogroups existed in West Asia and came to Europe in the Paleolithic, but more of them may have come during the Neolithic.

Thanks for the input. Does neolithic "always" imply a farming population, as opposed to a paleolithic being hunter-gatherer? The T mutation is said to have take place 10-15 k years ago.
