A 17-million-year-old Egyptian ape fossil challenges long-held ideas that modern apes evolved in East Africa

The discovery comes from Wadi Moghra, a fossil-rich area of northern Egypt where researchers recovered pieces of a lower jaw and several teeth belonging to a previously unknown ape. The species has been named Masripithecus moghraensis, with its name combining “Masr,” the Arabic name for Egypt, and the Greek word for ape. The fossils date to between 17 million and 18 million years ago, placing the animal in the Early Miocene. More importantly, researchers' combined analysis of fossil anatomy and molecular data from living species places Masripithecus unusually close to the evolutionary branch leading toward modern apes.

Egypt enters the early ape story

For decades, much of the fossil evidence used to reconstruct early ape evolution has come from East Africa. The Egyptian discovery does not prove that humans or modern apes originated in Egypt, but it adds an important piece to a much broader geographic puzzle. The fossil record from the Early Miocene has been particularly important for understanding how apes diversified. According to the Natural History Museum, the new species fills a significant gap in the fossil record and appears to sit close to the base of the evolutionary group containing living apes.

National Geographic reported that the fossils predate the period when ancient apes are known to have spread from Africa into Eurasia. The discovery therefore raises the possibility that the northeastern part of Africa and the adjoining Middle East could have been an important evolutionary crossroads. Shorouq Al-Ashqar, a palaeontologist at Mansoura University and one of the study's authors, told National Geographic, “we believe it’s the closest relative to the living apes and their ancestors” among known hominoid fossils.

What did the teeth reveal?

Scientists have only a limited amount of Masripithecus material, but the jaw and teeth provide valuable clues. The animal had a relatively robust lower jaw, prominent canine and premolar teeth and molars with rounded, heavily wrinkled chewing surfaces. Researchers believe these characteristics distinguish it from other apes known from the same period.

Science News reported that the thickness of the animal's tooth enamel suggests it may have eaten a mixture of fruits, nuts and seeds. That would fit with the forests that covered parts of what is now Egypt during the Early Miocene, when the region looked dramatically different from today's arid landscape. The finding also highlights how much of evolutionary history remains hidden. Wadi Moghra had been known as a fossil locality for roughly a century, yet this is the first definitive fossil ape identified from North Africa.

East Africa is not simply written out

The discovery does not mean scientists can now declare Egypt the birthplace of modern apes. Instead, it challenges a geographic assumption created partly by where fossils have been discovered. The researchers' analysis suggests that the ancestors of modern apes may have originated somewhere in northeastern Africa or the wider Afro-Arabian region rather than exclusively in East Africa or Eurasia. But the fossil record remains incomplete, and additional discoveries will be needed to test that scenario. That uncertainty is important because Masripithecus is known primarily from jaw and dental remains. A more complete skeleton could reveal features that teeth alone cannot.

A new target for fossil hunters

The significance of the Egyptian discovery may ultimately extend beyond one newly named species. It points scientists toward regions that have received less attention in the search for early ape fossils. As the Natural History Museum put it, the discovery opens “a new chapter” in the story of apes, including humans, beginning around 18 million years ago in North Africa.

For now, Masripithecus is not the final answer to where the modern ape lineage began. Instead, its fossilised jaw does something perhaps more valuable: it moves the map of the search. A desert landscape in northern Egypt has produced evidence suggesting that the roots of the living ape family may have extended through a much wider region than scientists once thought—and future fossils could determine just how far that story reaches.
