| Research Abstract |
The present molecular phylogenetic analyses revealed that lineages of rabbits, moles, mustelids, and lepolids have diverged at 500-600 and 200-300 million years ago and extended their lineages to Southeast Asia, India, Myanmar, and East Asia, including the Japanese Islands. In a analysis on a coat color related gene, Mc1r, a high proportion of nonsynonymous to synonymous substitutions was found on the ancestral stem of the subgenus Mus, perhaps because of its rapid habitat change during the course of its evolution.
