European genetic structure

There's been two recent papers that look at the relationship between geography/ethnicity and genetics in Europe. Dienekes has some excellent posts and pictures of these two papers (here, here), as well as at GNXP (here, here, here).

from the Nature paper:
an individual's DNA can be used to infer their geographic origin with surprising accuracy--often to within a few hundred kilometres.
and from a news story:
The map was so accurate that when Novembre's team placed a geopolitical map over their genetic "map", half of the genomes landed within 310 kilometres of their country of origin, while 90% fell within 700 km.
