I don't usually focus on animals, but I just spotted a really interesting paper on woolly mammoths (see here). Based on mtDNA extracted from a wide range of mammoth remains, it argues for a major migration of North American wooly mammoths to Siberia and then into Europe. Apparently, this population movement eventually resulted in the complete replacement of Siberian and European-specific mammoth mtDNA lineages with those from North America. However, it seems that European mammoths went extinct just before the arrival or their North American cousins west of the Urals. In any case, what I'm wondering is whether any Paleo-Siberian and indeed Paleo-Amerindian hunters followed these giant mammals into Northern Europe?
Following the expansion from North America to Eurasia, clade I appears to have been sympatric with clade II in Central and East Siberia until the demise of the latter (figure 3; see also [6,10]). Based on finite radiocarbon dates from clade II specimens, it seems that this clade disappeared around 45 kyr BP (although it should be noted that one clade II specimen has yielded an infinite date of more than 33 000 14C years, roughly corresponding to more than 37.5 kyr BP). Furthermore, clade I woolly mammoths continued expanding to the west, all the way to Europe, where they replaced the endemic population carrying mtDNA clade III (figure 3). Clade III disappeared from the fossil record at ca 34 kyr BP, whereas clade I seems to have made its first appearance in Europe at ca 32 kyr BP (see electronic supplementary material, table S1).
