"This tells us this H1 was part of a population that was rapid groniwg, and the best fit for that type of growth is farmers expanding into new territory. U5a has only 2 first level subclades, U5a1 and U5a2. So this indicates that U5a lived in a population that was groniwg very slowly. The other nodes in U5a descend from U5a1 and U5a2, and while the pace of expansion begins to increase at the next level, it is still very slow compared to the explosive population growth we see in H subclades" But the time of expansion of those two haplogroups could coincide. The number of steps from basal R is much the same for each haplogroup. U is a basal R haplogroup and so the U1, U5, U6 and U2'3'4'7'8'9 split is ancient within U. So the expansion within U5 (and possibly the other U clades) would be early. On the other hand H1 is several steps removed from basal R for a start. From R0 we have R0a'b and HV. From there we have several branches of HV including H itself. From where we get H1 and its subsequent expansion.
