Early Apes May Not Have Evolved in East Africa

Why It Matters

If early apes evolved outside East Africa, the prevailing model of ape and human origins must be revised, affecting evolutionary timelines and biogeographic reconstructions.

Key Takeaways

• 17‑million‑year‑old ape discovered in northern Egypt.
• New genus named Masripithecus moghraensis.
• Fossil suggests apes may have originated north of East Africa.
• Findings challenge East‑Africa‑centric ape evolution model.
• Region’s fossil record remains under‑sampled, promising more discoveries.

Pulse Analysis

The 2024 excavation at Wadi Moghra in Egypt yielded a lower‑jaw fragment bearing a distinctive flat wisdom tooth, a hallmark of apes rather than monkeys. Paleontologists led by Shorouq Al‑Ashqar identified the specimen as belonging to a previously unknown genus, Masripithecus moghraensis, dating to roughly 17‑18 million years ago in the Early Miocene. Enamel thickness indicates a mixed diet of fruits, nuts and seeds, consistent with the subtropical forests that once covered the region. This rare find is the first definitive ape fossil from North Africa, a continent previously known only for early monkey remains of the same age.

Integrating the fossil’s morphology with genomic data from living apes, the research team reconstructed a family tree that places Masripithecus near the last common ancestor of modern great apes. The statistical models suggest that early apes may have originated in the northern part of Africa or the Arabian Peninsula before dispersing eastward into Eurasia, with some lineages later returning to sub‑Saharan Africa. This scenario overturns the long‑standing East‑Africa‑centric narrative and forces a reevaluation of migration routes, climate influences, and ecological niches that shaped ape evolution during the Miocene.

The discovery underscores how sparsely sampled regions can conceal critical chapters of our evolutionary history. Countries such as Morocco, Tunisia and Libya host similar sedimentary basins that remain largely unexplored, promising additional fossils that could fill existing gaps. For paleoanthropologists, a broader geographic perspective may refine estimates of divergence times for hominins and clarify the environmental pressures that drove early ape diversification. As fieldwork expands beyond traditional hotspots, the emerging picture of ape origins will likely become more complex, enriching our understanding of the deep roots of the human lineage.
