not yet another musk ox in my garden!

Here is a map of the estimated range of the musk ox at various epochs, hence meaning one could indeed have visited my garden about 30,000 years ago… This map is extracted from a very interesting paper by Lorenzen et al. that just appeared in Nature. The main theme of the paper is to determine whether or not human intervention had an impact on the total or partial extinction of species on Earth. Their conclusion is that this only seems to be the case for European horses and bisons. This came to my attention because of Scott Sisson’s tweet on this paper. Given that it involves ABC technology, in particular ABC model choice based on solely four summary statistics (nucleotide diversity, Tajima’s D, haplotypic diversity, and Fst) and posterior probabilities. I wonder if this fits our requirement for convergence.
