Late Pleistocene polar bear genomes reveal the timing of allele fixation in key genes associated with Arctic adaptation
Y. Sun, E. Lorenzen, M. V. Westbury
This study uses Late Pleistocene polar bear genomes to assess the timing of allele fixation in key Arctic adaptation genes, finding most alleles were fixed before 70,000 years ago, with some recent fixes in APOB, LYST, and TTN.
