Ardipithecus Ramidus

In addition, the upper blades of Ardi's pelvis are shorter and wider in length in contrast of the upper blades of apes (Ann Gibbons 39). Ardi's spine resembled to a human's spine, in other words it was both long and curved instead of short and stiff like what a chimpanzee's would look like (Ann Gibbons 39). Therefore, these modifications suggested to C. O Lovejoy that Ar. ramidus had been bipedal for an extended timeframe (Ann Gibbons 39). Even so, the lower pelvis is enormous and sophisticated alike to African apes instead of hominins (Ann Gibbons 39). Ardi's opposable big toe and sophisticated characteristics within their hands and feet determined that Ardi didn't walk similar to Lucy and still spent an extended
Ardipithecus ramidus weighed about 50 kg and stood about 120 cm tall (). In the circumstances of the other saved hominids of this particular species, this suggested small body size difference between both males and females (). Ardi's brain size was as small as those of the living chimpanzees with regard to their mobility and dietary adaptations (). The numerous saved teeth and enormous complete cranium revealed that Ardipithecus ramidus had a small face including a reduced canine/premolar complex ().
The evidence of Ardi's hands, arms, feet, pelvis, and legs all together showed Ardi was able to move among the trees, was supported by her feet including her palms (palmigrade clambering), yet somehow didn't obtain chimpanzees and gorillas hanging, vertical climbing, or knuckle walking traits ().
Terrestrially, Ardi was involved with a form of bipedality that was considered to be primitive than those of the Australopithecus species (). Furthermore, Ardi did not adaptat to "heavy" chewing related to open environments (). Therefore, Ardipithecus ramidus determined the last common ancestors of humans and African apes were not similar to chimpanzees at all (). Thus, Ardipithecus ramidus, chimpanzees, and gorillas are
