The evolutionary history and molecular systematics of the Musteloidea
This chapter provides a review of the evolutionary and taxonomic history of the Musteloidea, which is the most species-rich superfamily of the Carnivora, containing approximately 30% of the extant species in the order. An up-to-date summary of knowledge on the evolutionary and taxonomic history and phylogenetic relationships of the Mephitidae, Ailuridae, Procyonidae and Mustelidae is provided. Multilocus DNA sequences have made a large impact on the understanding of phylogenetic relationships among the Musteloidea. Molecular data have revealed distinct families (Ailuridae and Mephitidae) within the Musteloidea and have illuminated new relationships based on tempo and patterns of evolution within the Procyonidae. Morphological data in conjunction with molecular data have been used to elucidate species boundaries within certain musteloid genera and have led to the discovery of a new species. Research studies published during the last 30 years have enriched and transformed our understanding of the evolution of musteloid biodiversity.
