Abstract：
:There is a huge data base of genetic information for the domestic artiodactyl species Bos taurus (cow), Ovis aries (sheep), and Capra hircus (goat). However, the phylogenetic relationships of these economically critical taxa and their close relatives, family Bovidae, remain for the most part unresolved. In this report, we aligned new mitochondrial (mt) 12S and 16S ribosomal (r) DNA sequences from 26 bovid taxa with published sequences. Phylogenetic analyses of the more than 64 kilobases of mt rDNA from 57 taxa support a basal division in the Bovidae that separates Bos and its close relatives from Capra, Ovis, and their kin. As suggested by previous molecular and morphological studies, "antelopes" are a paraphyletic assemblage. Caprinae (sheep, goats, goat antelopes, and musk oxen) groups consistently with hippotragine and alcelaphine antelopes, while Bovini (cattle and buffaloes) clusters with tragelaphine and boselaphine antelopes. The traditional tribal subdivisions of Bovidae are supported in most cases, but there are exceptions within Caprinae and Antilopinae (gazelles and close relatives). The rDNA data consistently place the enigmatic genera Pelea, Pantholops, and Saiga, but the origin of Aepyceros, the impala, remains obscure. Combined phylogenetic analyses of the rDNA data with the skeletal characters of Gentry (1992) were used to assess the stability of the molecular results.
