postglacial recolonization

Wednesday 28 September 2005

- Uncommon subhaplogroup pre*V tends to be scattered throughout Europe (and northwestern Africa)

- Haplogroup V attains two peaks of frequency: one situated in southwestern Europe and one in the Saami of northern Scandinavia.

- Geographical distributions and ages support the scenario that pre*V originated in Europe before the Last Glacial Maximum (LGM), whereas the more recently derived haplogroup V arose in a southwestern European refugium soon after the LGM.

- The arrival of Haplogroup V in eastern/central Europe, however, occurred much later, possibly with (post-)Neolithic contacts.

- The distribution of haplogroup V mtDNAs in modern European populations would thus, at least in part, reflect the pattern of postglacial human recolonization from that refugium, affecting even the Saami.
