Looking at ancient samples in MTree I saw that haplogroup R0(basal to HV) only appears in Scottland and Egypt.

The funny thing is that on the other hand we don't see HV in Europe until the German Neolithic, but we see them for the first time in Tell Halula(Syria) and Ganj Dareh(Iran).

Something that makes me think R0 appeared in NW Europe in the LGM or so and then migrated into the Middle East, where it became HV.
