Phylogenetic analysis of the tribe Bovini (Mammalia: Artiodactyla)

A matrix of 57 (mainly cranial) characters and 32 taxa of fossil and Recent Bovini (buffaloes, bison and cattle) has been analysed using the parsimony program HENNIG86. Among the best established results are the exclusion of Parabos, polyphyly of Leptobos, monophyly of the Bos sensu lato + buffaloes group (a clade including all Recent Bovini), probable monophyly of the Bubalina and Syncerina, and the close relationship between bison and yak. Some other interesting questions raised include the apparent absence of a close link between Pliocene African bovines (except “Leptobos” syrticus) and later African buffaloes, and the possible monophyly of Pelorovis oldowayensis+Bos sensu lato.
