Ancient Primate Fossil Rewrites Human Evolution Story | SciencePost

A newly discovered fossil ape in northern Egypt is challenging long-held beliefs about the origins of modern apes and humans. The primate, named Masripithecus moghraensis, lived approximately 17 to 18 million years ago during the Early Miocene epoch and its discovery suggests that the evolutionary roots of apes may lie in North Africa and the Middle East, rather than exclusively in East Africa.

A New Primate Emerges

The remains of Masripithecus moghraensis were unearthed at the Wadi Moghra site in the Qattara Depression of northern Egypt between 2023 and 2024. The fossils consist of fragments of a lower jawbone and teeth. Analysis of these remains, detailed in a study published in the journal Science on March 26, 2026, indicates that this primate represents a previously unknown genus and species.

“We spent five years searching for this kind of fossil because, when we look closely at the early ape family tree, it becomes clear that something is missing—and North Africa holds that missing piece,” said Hesham Sallam, a paleontologist at Mansoura University in Egypt and senior author of the study, according to a report from Mansoura University.

Positioning in the Ape Family Tree

Researchers utilized advanced techniques combining dental anatomy and analysis of the DNA of living ape species to determine M. Moghraensis’s place in the evolutionary tree. The analysis places the new species at a crucial juncture, just before the divergence between “great apes” – including humans, chimpanzees, and gorillas – and “lesser apes” – such as gibbons and siamangs.

This positioning suggests that the last common ancestor of all living apes may have resided in the Afro-Arabian region, rather than solely in East Africa. This would provide a more plausible explanation for the relatively rapid dispersal of apes into Europe and Asia during the Early Miocene, utilizing the northeastern part of the continent as a migratory pathway.

A Potential Biogeographic Crossroads

The discovery of Masripithecus moghraensis is particularly significant because it represents the first definitive fossil ape found in North Africa. Previously, fossil evidence from this region consisted primarily of monkeys, leading scientists to believe that apes were largely confined to southern Africa during the Early Miocene. The finding expands the known geographic range of early apes and highlights the potential importance of the Middle East as a center for hominoid evolution.

According to the Wikipedia entry updated on March 30, 2026, Masripithecus is considered closer to basal hominoids than its contemporaries from East Africa.

Scientific Debate and Future Research

The interpretation of the findings has sparked debate within the scientific community. While many experts praise the discovery of such a rare fossil, others remain cautious. Some argue that the limited fossil material – consisting of only jaw fragments and teeth – is insufficient to overturn the established view of East Africa as the primary cradle of ape evolution.

However, researchers like Shorouq Al-Ashqar emphasize the reliability of dental enamel as a record of evolutionary history. Further excavations at Wadi Moghra and other sites in the Egyptian desert are planned, with the hope of uncovering additional fossils that could provide further evidence to support this new understanding of ape origins. The Mansoura University Vertebrate Paleontology Center and the University of Southern California are collaborating on these ongoing research efforts.
