  On the base of advantages in gene geography and anthropophenetics the
phenogeographical method for anthropological research is initiated and
experienced using dental data. Statistical and cartographical analyses are
provided for 498 living Eurasian populations. Mapping principal components
supplied evidence for the phene pool structure in Eurasian populations and for
reconstructions of our species history on the continent. The longitudinal
variability seems to be the most important regularity revealed by principal
components analysis (PCA) and mapping proving the division of the whole area
into western and eastern main provinces. So, the most ancient scenario in the
history of Eurasian populations was developing from two perspective different
groups: western group related to ancient populations of West Asia and the
eastern one rooted by ancestry in South and/or East Asia. In spite of the
enormous territory and the revealed divergence the populations of the continent
have undergone wide scale and intensive time-space interaction. Many details in
the revealed landscapes could be backgrounded to different historical events.
The most amazing results are obtained for proving migrations and assimilation
as two essential phenomena in Eurasian history: the wide spread of the western
combination through the whole continent till the Pacific coastline and the
envision of the movement of the paradox combinations of eastern and western
markers from South or Central Asia to the east and to the west. Taking into
account that no additional eastern combinations in the total variation in Asian
groups have been found but mixed or western markers' sets and that eastern
dental characteristics are traced in Asia since Homo erectus, the assumption is
made in favour of the hetero-level assimilation in the Eastern province and of
net-like evolution of our species.
