In this paper, I discussed about the fact that infant of anthropoid has alredy tendency to keep erect posture, and that human erect, too. So I wish to assert that characters of hominids and infant of hominoids are homology, and that hominids is neotenic species of infant of hominoids: This is a reason why human keeps erect posture and bipedal walk.
