hi,
i uploaded one of the most recent papers under the genetics folder of
the files section. maybe i am unclear on my understanding of the
various hypotheses regarding indoeuropean expansion, but i think the
data supports a significant role for the location north of the black
sea in its dispersal.

ABSTRACT: Previous studies on human Y-chromosome
polymorphisms in the European populations highlighted
the high frequency of the 49a,f/TaqI haplotype 11 and of
the Eu19 (M17) lineage in Eastern Europe. To better
understand the origin and the evolution of the Eu19, and
its relationship with 49a,f Ht11, this study surveyed
2,235 individuals (mainly from Europe and the Middle
East) for the 49a,f Ht11 and for many biallelic markers
defining the Eu19 lineage. As previously described, the
highest frequency of Eu19 was found in Eastern Europe.
All the Eu19 Y-chromosomes turned out to be 49a,f Ht11
or its derivatives, the distribution of which suggests that
the Eu19/49a,f Ht11 emerged in Ukraine, probably in a
Palaeolithic population. Thereafter, the spread of this
lineage toward Europe, Asia, and India occurred at different
waves over a few thousands years. At present this
seems to indicate the influence of the Ukraine Palaeolithic
groups in the gene pool of modern populations. For the
first time it is possible to make inferences about the
evolution of some haplotypes of the 49a,f system. In spite
of its unknown molecular base, this is one of the first most
informative polymorphisms of the Y chromosome.
