The discovery of Masripithecus moghraensis, a previously unknown primate species unearthed in Egypt’s Wadi Moghra, challenges long-standing theories regarding the origins of hominoids. According to a study published March 26 in the journal Science, these 18-to-17-million-year-old fossils suggest that the common ancestors of humans and modern apes may have originated in North Africa before migrating to Eurasia, rather than exclusively evolving in East Africa.
Rewriting the Evolutionary Map
For decades, the prevailing scientific consensus held that early hominoids—the group including humans, gorillas, chimpanzees, and orangutans—emerged in East Africa. Researchers previously estimated that these ancestors migrated to Europe during the Middle Miocene, roughly during the middle Miocene epoch. However, the discovery of Masripithecus moghraensis shifts this narrative.
By identifying these remains in North Africa, the research team provides evidence that the evolutionary cradle of these primates may be further north than previously documented. This finding suggests a broader geographic range for early hominoids and offers a new timeline for their eventual expansion into Eurasia.
The fossils consist of lower jaw segments and teeth. Despite the harsh, arid conditions of the Wadi Moghra region, the team successfully utilized 3D modeling to reconstruct the jaw, revealing anatomical features that closely resemble early human bone structures.
The Discovery at Wadi Moghra
While the Wadi Moghra region had previously yielded fossils of smaller, tailed monkeys, no hominoid remains had ever been recovered from the site.
The breakthrough occurred during a routine search of the valley. Al-Ashkar identified a fragment of a lower jaw that, upon inspection, displayed characteristics distinct from the monkey fossils typically found in the area. Sallam described the moment of discovery, noting that the bone’s morphology was strikingly similar to human skeletal remains. This discovery effectively confirms the presence of hominoids in North Africa during a critical period of primate evolution.
