The foot bones in this skeleton indicate a divergent large toe combined with a rigid foot – it's still unclear what this means concerning bipedal behavior. The ischium of Ardipithecus ramidus is longer which is similar to living apes (Gruss, Schmitt, 2015). Given the predominant absence of derived traits in other skeletal regions of Ar. These changes are shared with some Middle and Late Miocene apes as well as with African apes and later hominids. ramidus shows that it was still climbing trees, on the ground it walked upright.
