Protein evidence reveals hidden variation in P. robustus. The species may be more complex than once believed. For close to a hundred years, researchers have examined puzzling fossils belonging to a distant and unusually robust relative of early humans, known as Paranthropus robustus. This upright-walking species was adapted for powerful chewing, equipped with large jaws […]



Summary

New protein analysis of Paranthropus robustus fossils suggests the species is more diverse than previously thought. For nearly a century, scientists have studied the robust, large-jawed hominin species, believed to be well-adapted for chewing. However, the protein evidence reveals subtle but significant variations within the species, implying a greater complexity than initially recognized based solely on skeletal remains. This challenges previous understandings and opens new avenues for research into the evolution and potential sub-species within P. robustus.
