Endangered horse has ancient origins and high genetic diversity, new study finds

An endangered species, Przewalski's horse, is much more distantly related to the domestic horse and has a much more diverse gene pool than researchers previously had hypothesized, researchers report. The new study's findings could be used to inform conservation efforts to save the endangered species, of which only 2,000 individuals remain in parts of China and Mongolia, and in wildlife reserves in California and the Ukraine.
