 Besides manifesting lesser prognathism than the australopithecines, OH 24 also portrays a larger cranial vault, indicating an expansion in brain size from its ancestor, and the reduction of facial prognathisim typical of the evolution of early "Homo".The individual's third molars had erupted, which indicates that OH 24- "Twiggy" was an adult at death.Yet, these molars show no sign of wear ( the points on the crowns of the teeth are still sharp, and show little sign of abrasion by rough food matter), indicating that this individual died soon after the eruption of these molars.
