Abstract in brief

  • Paranthropus boisei, an early Pleistocene hominin from East Africa, had specialized skull and teeth features that suggest it was adapted to eating hard objects, but recent evidence indicates its diet mainly consisted of C4 plants like grasses and sedges.
  • Stable isotope analysis shows P. boisei consumed more C4 biomass than any other studied hominin, implying a diet heavily based on low-quality vegetation rather than tough foods.
  • Dental microwear and isotopic data together suggest that the distinctive cranio-dental traits of P. boisei may have evolved primarily for processing large amounts of fibrous, low-nutrient plants rather than hard objects.]
