GENUS Bos
| Author: | Linnaeus, 1758. | | Citation: | Syst. Nat., 10th ed., 1: 71. | | Type Species: | Bos taurus Linnaeus, 1758. | | Comments: | Includes Bibos, Novibos, and Poephagus; see Ellerman and Morrison-Scott (1951:380). Genus traditionally comprises B. frontalis or Bibos group (includes also B. javanicus and B. sauveli), B. taurus or nominate Bos group, and B. grunniens or Poephagus group. From cranial morphometrics Groves (1981d) suggested that Bibos group is paraphyletic, B. sauveli is related to B. taurus, and Bison should be included in Bos. From mtDNA sequences, the most parsimonious cladogram suggested that Poephagus plus Bison formed the sister-group of domestic cattle, but Bibos was not studied (Miyamoto et al., 1989). From cranial morphometrics, Geraads (1992) suggested Bison plus Poephagus is the sister-group of Bibos plus nominate Bos, with Bibos paraphyletic.Using restriction-site mapping of nuclear-ribosomal DNA regions, Wall et al. (1992) came to similar conclusions but with the position of Poephagus unresolved and "Bibos" species, Bos javanicus and Bos gaurus (= frontalis), sister species. |
