"Gail, are we reading the same paper? Fig. 4 shows a star ptreatn in U5a with 26 unique positions. H1 is not even plotted" If you look at first level subclades, H1 has approximately 70, from H1a to H1bz, and it also has a large number of H1* samples that have not yet been given a name - thus my reference to nearly 100 unique daughters. That is a true star patter, nearly 100 lines radiating out. This tells us this H1 was part of a population that was rapid growing, 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 growing 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. So there is something very qualitatively different about H1 and U5a.
