Artiodactylan phylogeny: an immunogenetic study based on comparative determinant analysis.
The phylogenetic relationships of major artiodactylan taxa were investigated by means of comparative determinant analysis (CDA). Monospecific antisera against taurine cattle albumin, transferrin, C3 and IgM were used to derive determinant formulas of their homologues in 21 species (plus 12 other mammals for outgroup comparison). Fifteen accepted mutations could be demonstrated in Artiodactyla, permitting recognition of nine immunologically defined species groups. Results with phylogenetically relevant implications include the clear immunogenetic separation of the vicugna from true ruminants, a complex pattern of accepted mutations rendering a genealogical analysis of the principal pecoran radiation difficult, one synapomorphic mutation combining the goitred gazelle with bovines but excluding Caprinae, and the immunological recognition of the three grades of wild cattle evolution. This study demonstrates the suitability of CDA as a tool of phylogenetic systematics above the level of genera.
