This unexpected large evolutionary distance between these two geographic groups of the Asian Black Bear probably deserves further study. (sciencedaily.com)
However, the identification of conserved male or female - specific gametogenic proteins across large evolutionary distances could uncover molecular traces of any ancient gametogenic machinery, providing evidence for a common origin of sexually dimorphic traits among animals. (journals.plos.org)
Fish and humans represent about the same evolutionary distance as rice and moss. (sciencemag.org)
