Sarmiento noted that " Ardipithecus " does not share any characters exclusive to humans and some of its characters ( those in the wrist and basicranium ) suggest it diverged from the common human / African ape stock prior to the human, chimpanzee and gorilla divergence His comparative ( narrow allometry ) study in 2011 on the molar and body segment lengths ( which included living primates of similar body size ) noted that some dimensions including short upper limbs, and metacarpals are reminiscent of humans, but other dimensions such as long toes and relative molar surface area are great ape-like.
