An Early Miocene ape from the biogeographic crossroads of African and Eurasian Hominoidea
Abstract
The Early Miocene fossil record documenting hominoid evolution has long been restricted primarily to sites in East Africa, whereas contemporaneous North African sites have only yielded remains of cercopithecoid monkeys. Here, we describe a fossil ape from North Africa, a new genus ( Masripithecus ) from the Early Miocene (~17 million to 18 million years) of northern Egypt, on the basis of mandibular remains. A combined molecular-morphological Bayesian tip-dating analysis positions Masripithecus closer to crown hominoids than coeval fossil apes from East Africa, thereby filling a phylogenetic and biogeographic gap in the evolution of stem hominoids. This evidence suggests that crown Hominoidea might have originated during the Early Miocene in the underexplored northeastern part of Afro-Arabia, rather than in eastern Africa or Eurasia.
