Australopithecus ramidus
Australopithecus ramidusAlso known as Ardi, Root Ape
Ardipithecus ramidus walked upright across the woodland floors of Pliocene East Africa while retaining grasping big toes well-suited for climbing high into the forest canopy. Reduced canines in both sexes suggest social structures marked by lower aggression compared to modern chimpanzees. Skeletal evidence indicates a flexible omnivore adapted to foraging on woodland vegetation, tree fruits, and soft browse rather than tough savanna grasses.
