PosturePongidHominid Bent over or quadrapedal; Knuckle walking common Upright or bipedal
Leg and Arm PongidHominid Arms longer than legs, adapted for swinging by arm usually among trees Legs usually longer than arms; adapted for striding
FeetPongidHominid Low arches; opposable big toes capable of grasping High arches; big toes in line with others; adapted for walking
TeethPongidHominid Prominent; large gaps between canines and nearby teeth Reduced; reduced or absent gaps
SkullPongidHominid Bent forward from spinal column; very rugged; prominent brow ridges Upright on spinal column; smooth brow ridges
FacePongidHominid Jaws jut out; very heavy; very wide nasal opening; sloping Vertical profile; More distinct chin; Prominent nasal spine

Hominid Evolution. Physical features that define humans as primates: grasping limbs with opposable thumb strong mobile arms/shoulders stereoscopic vision.
Probably first appeared about 200,000 years ago. Paleoanthropologists study human evolution. There is sparse evidence relating to the evolution.
