Ardipithecus
Anthropologists have found the remains to what they classified as a distinct genus they called Ardipithecus. Ardipithecus has many characteristics that some may consider to be a hominid but there are also some evidence that point to the other direction that Arditpithecus is not a hominid. It is the most apelike hominid ancestor known (Boaz and Almquist, 2002). Ardipithecus is the earliest potential hominid found so far and was discovered in Ethiopia in 1994 by Tim White and his colleagues. So where exactly were these fossils found? These fossils were found in a dense forest with a relatively cool and wet climate. In contrast, early hominids were found in a savannalike setting (Boaz and Almquist, 2002). The origin of bipedalism took place in the savanna. Our ancestors were more adapted in opened grasslands. They left the trees and become bipedal. Bipedalism is considered the essential feature of being human. Therefore, from this I can conclude that Ardipithecus is not a hominid. However, there could be that little chance that Ardipithecus did migrate to the forest bipedally or because there was a climate change, which caused the forest to turn into a savanna. On the other hand, Bernard Wood, a professor of human or
As for Ardipithecus, their femur does not have a lump or groove at the end to prevent the patella from sliding off the joint. The discovered fossils were trapped in sediments sandwiched between layers of volcanic ash, whose age can be figured out by a dating technique called Potassium/Argon dating. The reason why modern humans do not have diastemas is because humans lack projecting canines. But Ardipithecus does have big back teeth like Australopithecines. Its molars are truly massive, some are even twice the size of a modern human molar. igins at George Washington University, is questioning whether bipedalism is considered to be the defining characteristic of being human. However, it was enough for them to conclude that Ardipithecus is not a hominid. Not only are the Ardipithecus canines are absolutely larger, because males themselves are larger than females, but they are relatively larger as well. Like Orrorin tugenensis, both have apelike craniodental morphology, but the femur of both species differs. When compared to Australopithecus anamensis's teeth, they have a thicker enamel than those of Ardipithecus, long and robust root. Male human canines are larger than female ones only because their body is larger. Yet, due to the discovery of Ardipithecus fossils, the answer to the question of whether it is a hominid or not was answered. Tim White and his colleagues did not have much to work with. It was sexual dimorphorism in their canines. Human canines are relatively small and bluntly pointed.
