Subordinal artiodactyl relationships in the light of phylogenetic analysis of 12 mitochondrial protein-coding genes
Extant artiodactyls (even-toed hoofed mammals) are traditionally divided into three main lineages: Suiformes (pigs, peccaries and hippopotamuses), Tylopoda (camels and llamas) and Ruminantia (bovids, deer, tragulids and giraffes). Recent molecular studies have not supported a close relationship between pigs and hippopotamuses, however, instead grouping hippopotamuses with Cetacea (whales, dolphins and porpoises). In this study we […]
