I was always going to remember as soon as I logged off. Spencer Wells. Anyway if you haven't seen Cavalli-Sforza's maps I've found the European ones. No luck with the world yet:
http://www.pnas.org/cgi/content/full/94/15/7719/F2I suspect the first one reflects movement from northwest Europe as much as from the Middle East. If anyone wants an argument I'll explain why I think the second one has something to do with the separate Aurignacian and Gravettian movements into Europe. The third seems pretty safe to call Indo-European expansion. Fourth possibly the Sea People, almost certainly Greek, Southern Italy and Western Anatolia anyway. The fifth seems to show an expansion from around the North Sea and Baltic through to Anatolia. Anyone got any comments?
Can't find world maps but they are in "The History and Geography of Human Genes". Very interesting if you get a chance to glimpse them.
