Evidence of two genetically deeply divergent species of warthog, Phacochoerus africanus and P. aethiopicus (Artiodactyla: Suiformes) in East Africa

摘要: Two species of warthogs (Phacochoerus), differing by the number functional incisors, were described in Holocene fossil record: common warthog (P. africanus), widespread sub-Sahar-an Africa, and Cape, or desert aethiopicus), which was considered extinct since 1896, but recently rediscovered East Africa morphological analyses. Mitochondrial single-copy nuclear DNA sequences show that belong to two deeply divergent monophyletic lineages, might have originated last part Pliocene. The finding genetically extant highlights importance molecular methods applied knowledge conservation biodiversity uncover tempo mode its evolution.
