[Parasitological evidence on the phylogeny of hominids and cebids]

A systematic revision of the ectoparasites (lice) of the hominids and ceboids supports the Trogloditian hypothesis, according to which the genus Homo is the sister of Pan, and the genus Gorilla the sister group of both. The phylogenetic analysis of this matrix derived from the study of primate lice shows an C.I. of 0.71 for the Trogloditian hypothesis including the ceboids in the analysis.
