Representation of the modes of locomotion practiced by Sahelanthropus. Bipedalism was common among the earliest known representatives of the humankind, probably on the ground but also in trees. It coexisted with other types of movement in a tree environment, including quadrupedal movement using firm hand grips, clearly differing from that of gorillas and chimpanzees who use the back of their phalanges for support ("knuckle walking").
