A fossilized jawbone discovered in Ethiopia’s Afar Depression has been identified as belonging to the robust hominin genus Paranthropus, marking the first time this distinct human relative has been found in the fossil-rich region. Dated between 2.5 and 2.9 million years old, the partial mandible (cataloged as MLP-3000) was unearthed in the Mille-Logya area and is described in a new study published in Nature.
Paranthropus species, known for their massive teeth, powerful jaws, and specialized chewing adaptations, were previously documented from South Africa to southern Ethiopia but conspicuously absent from the Afar—a region famed for its wealth of early human fossils. This discovery extends the northernmost range of the genus by over 1,000 kilometers and confirms that Paranthropus was geographically widespread early in its evolution.
The findings challenge the long-held view of Paranthropus as a dietary specialist restricted to certain habitats. Instead, the genus appears to have been as ecologically flexible as its relatives Australopithecus and early Homo, occupying diverse environments across Africa. At around 2.6 million years old, the MLP-3000 mandible is also one of the earliest known Paranthropus fossils, offering new clues about the group’s origins and early physical characteristics.
Together with other recent discoveries in the Afar, the evidence now suggests that between 3.0 and 2.4 million years ago, this region was home to at least four distinct hominin lineages, including early Homo, Australopithecus garhi, another yet-unnamed Australopithecus species, and now Paranthropus. This remarkable diversity paints a more complex picture of early human evolution, in which multiple hominin species coexisted and possibly interacted across the same landscapes long before the rise of modern humans.
