Following the mammoth herds?
The recent Qiaomei Fu et al. paper on the population genomics of Ice Age Europe was a fascinating read, but its sampling strategy left a big blind spot: Eastern Europe 24-34 kyr BP. Check out what happens to the maternal lineages of Eastern European mammoths at this time. here). Perhaps mammoth hunters? No wonder then, that this is also the time when we see the first appearance of Y-chromosome haplogroup R1 in Europe; more precisely R1b1, in the ~14 kyr cal BP genome from Villabruna, northeast Italy, that defines the Villabruna cluster. After all, R is the sister clade of Q, the dominant Y-chromosome haplogroup in many parts of North Asia and the Americas. Image credit...
