The recent paper of A. Olivieri et al., Mitogenomes from Two Uncommon Haplogroups Mark Late Glacial/Postglacial Expansion from the Near east and Neolithic Dispersals within Europe, PLOS One, July 2013, not only states what we are being adfirming from many years (that if there was expansion from Middle East it happens so long ago, after the LGM and Neolithic, I'd say after the Younger Dryas as I am saying, and that Europe was peopled by inner moves rather than inputs from outside, and you know that for me these inner moves came from Italy above all), but, taking in consideration two rare halogroups (I and W), what we are doing from many years, they try to understand these inner moves.
What about these haplogroups, derived from N?
"Our results showed that haplogroups N1a1b1, I and W most probably originated in the Near East during the Last Glacial Maximum [...] and, like J and T, may have been involved in Late Glacial expansion starting from the Near East" (p. 3).
But which is the surprise?
"Moreover, at least nine paraphyletic mitogenomes (mainly from the Near East) do not fall within any of the seven major subclades of haplogroup W. In particular, the Italian sample #223, bearing a single reversion of the defining control-region variant at position 16292, might even possibly radiate before the root of the entire haplogroup W. However, the hypothesis of a founder haplotype from central Italy remains enigmatic and would need further evidence to be properly supported" ( p. 10)
