Ramana,
Oppenheimer titled a chapter 'two kinds of european'. This is a reference to a dual (mideast and indian) origin of every european line. The mideast ones tend to be earlier and correspond to the original settlement of europe (still delayed when compared to interior asia). The indian ones are even later (post-ice age). Ultimately, even the mideast contribution in Europeans is derived from S Asia, but since this event is so distant, it can be effectively ignored. Euros have very rarified lineages, very similar to beringia (and N Am) in its relation to rest of Asia. IOW, Beringia (and its sink N Am) has just a fraction of the diversity seen in Siberia and East Asia. Europe is very similar in its relation to rest of eurasia.
