Modern humans had spread into northern Europe, Russia and Siberia before the LGM, and there are two mtDNA haplogroup U5 samples dated at 31,155 years ago at Dolni Vestonice in the Czech Republic. This suggests continuity of Paleolithic humans in Europe, i.e., they retreated to southern refugia at the time of the LGM and then expanded north again as the ice retreated.

Originally posted by GST View PostWe have a very small amount of ancestry from Paleolithic Europeans who retreated to ice age refugia, but it's clear from the DNA evidence that there were multiple waves of migration into Europe from the Near East farmers and Steppe pastoralists in the Neolithic and metal ages. Of course, some of those Steppe pastorlists and Near East farmers may also have been partly descended from Ice-Age refugees. Much of the U5 in Europe today might be from Neolithic farmers and herders. I expect we will get more clarity on the amount contributed by each group when we have more ancient autosomal DNA.

R1b group spent 12,000 years as Ice-Age refugees but which refuge were they in? That is the big question.
