Relatively large bodied, long arms, short legs, no tail: live primarily on ground except orangutans, distinct way of walking: Fist walk - backs of hands pressed to ground. Also occasionally rise up on two legs - usually displaying aggression. Humans only living great ape fully bipedal: bipedalism is the synapomorphy that defines hominins. Hominins are monophyletic group comprising homosapiens and more than 20 extinct bipedal relatives. Species in genus homo are called humans: appearance of early members of genus homo coincides closely w/ appearance of tools made of worked stone - most interpreted as handheld choppers/knives.
