Ochotonids (commonly called pikas) are a group of small-sized lagomorphs, placed in the family Ochotonidae, and are most diversified in Asia, with only two species in North America and one in Europe. Though numerous fossil species have been found, only one genus of Ochotonidae, Ochotona, survives to the present. Fossil records indicate Asia was the center of origin for Ochotonidae. However, the divergence time of Ochotona is still unclear.
