Well, R1a was certainly in Europe (Ukraine) during the LGM according
to the prevailing view, and so was I1b (Balkans). As the ice
retreated, it would be easy for big-game hunters to move northwards
across the eastern European plain, colonizing previously unpopulated
lands, and these groups would spread R1a along with them. At the same
time, the I1a/R1b people moved along the Atlantic to Scandinavia;
their path would be similarly easy because of the generally mild
climate in Western Europe compared to continental Europe at the same
latitude. So, in Scandinavia there would be the convergence of two
repopulation movements following the easy access routes across the
eastern European plain and the Atlantic shore, explaining the presence
of I1a/R1b/R1a there. The progress of I1b from its landlocked
mountainous cradle would be slower, and would occur mainly later by
Neolithized groups.
