| Popis: | Portions of the 12S and 16S mitochondrial ribosomal genes for 16 species representing nine tribes in the mammal family Bovidae were compared with six previously published orthologous sequences. Phylogenetic analysis of variable nucleotide positions under different constraints and weighting schemes revealed no robust groupings among tribes. Consensus trees support previous hypotheses of monophyly for four clades, including the traditional subfamily Bovinae. However, the basal diversification of bovid tribes, which was largely unresolved by morphological, immunodiffusion, allozyme, and protein sequence data, remains unresolved with the addition of DNA sequence data. The intractability of this systematic problem is consistent with a rapid radiation of the major bovid groups. Several analyses of our data show that monophyly of the Bovidae, which was weakly supported by previous morphological and molecular work, is questionable. |
