- Abstract
Orliac, M. J., Antoine, P. -O., Ducrocq, S. (2010). Phylogenetic relationships of the Suidae (Mammalia, Cetartiodactyla): new insights on the relationships within Suoidea. — Zoologica Scripta, 39, 315–330. In most analyses, both molecular and morphological phylogenies of the Cetartiodactyla support the monophyly of Suoidea. However, the evolutionary history of this superfamily remains poorly known primarily due to long-lasting debates about the taxonomic content and relationships of the suoid families and subfamilies. Despite their crucial position in the reconstruction of the phylogeny of Cetartiodactyla, Suoidea themselves have received little attention in those phylogenies, and no extensive analysis of the group has been performed so far. We therefore examine the phylogeny of the Suidae through the first phylogenetic analysis of Suoidea, including recent and fossil representatives of all four putative families. The results support the monophyly of the traditional suid subfamilies and indicate the Sanitheriidae as sister taxon to the Suidae clade. The evolutionary history within Suidae reveals its complexity, with major convergences involving important morphological structures such as the auditory region or the upper male canine. Divergent signals gathered from either dental or cranio-mandibular features are responsible for two long-lasting unresolved issues within Suoidea: the question of the relationships between ‘Old World’ and ‘New World’ peccaries remaining unsolved, as well as the position and familial status of the mid-Tertiary tayassuid Perchoerus.
