Population labels have been printed in the co-ordinates of the
population averages; these largely correspond with identifiable
blobs of colored points, but note that some populations have
several outliers, so labels appear in white space. Most notable
in that respect are the Koryak, Chukchi, and the Nganasan, all
of whom have some apparently European-admixed individuals.
"Mongol" corresponds to Rasmussen et al. (2010) Mongol sample,
while "Mongola" to the HGDP-CEPH one. The population codes on
the left may not be clearly visible as they overlap with each
other and are CEU, LT, HU (relatively unadmixed Caucasoids),
FI/RU (Uralian-admixed northern Caucasoids), IR/TR (Altaic-
admixed southern Caucasoids). The West Eurasian part of the plot
can be seen blown up on the right. The correspondence with
geography and language is striking. Siberian isolates from the
extreme north and east, Koryak and Chuckhi are on top; HapMap
Chinese at the bottom. Between them are Uralians (Selkup,
Yukagir, Nganassan) and Altaics (Mon
