First definitive fossil ape in North Africa reshapes early evolution
An 18-million-year-old ape fossil discovered in Egypt challenges the long-held belief that modern apes evolved in East Africa, suggesting North Africa and the Middle East were the evolutionary cradle.
A 17- to 18-million-year-old ape fossil discovered in Egypt is challenging long-held beliefs about where the ancestors of humans and other modern apes first evolved. The fossil of Masripithecus moghraensis, a previously unknown species, represents the first definitive fossil ape found in North Africa. It consists only of lower jaw material and was unearthed in the Wadi Moghra area of northern Egypt's Mansoura region during expeditions in 2023 and 2024.
The study was led by Hesham Sallam of the Mansoura University Vertebrate Paleontology Center and Erik Seiffert of the University of Southern California. It was published on March 26, 2026, in the journal Science, confirming the find's significance through peer-reviewed research. The fossil dates to the Early Miocene epoch, a period from 23 to 16 million years ago when the common ancestor of all living apes is estimated to have lived. Earlier theories had placed early ape evolution primarily in East or southern Africa.
Scientific validation and publication details
The research team included scientists from Egypt and the United States. They used Bayesian methods to analyze the fossil's evolutionary relationships, combining anatomical, genetic, and geological data. The analysis placed Masripithecus moghraensis as a close relative of the last common ancestor of all living apes, a group known as crown Hominoidea. The fossil record for North Africa's Early Miocene had previously only provided evidence of monkeys, making this ape discovery a key shift.
Dietary adaptations and evolutionary implications
The jaw structure reveals specific dietary adaptations. It shows robust canines and premolars, with rounded, textured molars. Researchers believe the animal primarily ate fruit but possessed the dental machinery to process tougher foods like nuts or seeds when necessary. These adaptations suggest a flexible, fruit-based diet with a backup capacity for harder items, indicating diverse feeding strategies were already present in early apes.
Rethinking early ape evolution geography
The discovery directly challenges the assumption that East Africa was the primary center of early ape evolution. Instead, the research suggests northern Africa and the Middle East may have been the central geographic nexus for the emergence of crown Hominoidea. The fossil site is part of a region where the African and Arabian tectonic plates were interacting and moving northward during the Early Miocene. Sea level changes from this tectonic activity may have facilitated movement between Africa and Eurasia, allowing apes to disperse from a North African hub into Europe and Asia.
Scientists state that Masripithecus is not a direct ancestor of humans or modern great apes, but it illuminates the broader evolutionary context of ape ancestry. The findings suggest North Africa may have been a previously overlooked center of evolutionary diversification for apes. Continued exploration in North Africa is needed to fully understand the significance of this find and to uncover more of this hidden chapter in primate history.
