The Discovery of Ardipithecus Kadabba, the Oldest Hominid :: Anthropology Essays Paleontology Papers

The Discovery of Ardipithecus Kadabba, the Oldest hominianDuring an excavation in the middle Awash Region of Ethiopia, Haille- Sellaise unearthed six human teeth. These were at first thought to be the fossilized teeth of Ardipithecus Ramidus. The teeth have now been determined to be from the late Miocene, and those of Ardipithecus Kadabba. These are the oldest hominid remains found, to date. Upon earlier digs in this region between 1997 and 2000, Haille- Sellasie sight an earlier tooth and fragments of an arm bone. These remains were first thought to be those belong to Ardipithecus Ramidus Kadabba, a subspecies of a younger hominid (Science Daily). However, after the progress recent teeth discoveries it has been decidedly evident that these belong to Ardipithecus Ramidus. The hominid has seemly evidence to be its own species rather than a subspecies of Ardipithecus Ramidus Kadabba, as earlier thought. This could possibly mean that The new fossils show the most native d ogs-tooth violets ever found among hominids (Science Daily). Much can be told about the modus vivendi of an animal through the wear and acquired shape of their teeth. In the case of Ardipithecus Kadabba this implicates that this species whitethorn be the first divergence from the chimpanzee line. In the apes, the upper canine is continually honed against the lower third premolar to keep it sharp. Human canines leave out this function (Sanders). What is gathered from this information is that the teeth of Ardipithecus Kadabba may be that of the oldest cognize hominids, and the first to branch off from chimpanzees. Also an implication may be that the newly evolved hominids were living in radically different, less competitive well-disposed structure than seen in modern chimps (Sanders). The sharp canine would probably be used to injure, and in fights between males in hopes to impress females. In forthwiths chimps the situation that Ardipithecus Kadabba (as closely related to chimpanzees as it is) lacks this feature is an index number of this. The Ardipithecus Kadabba is thought to be a bipedal hominid. Bipediality involves a large and colonial set of anatomical traits and is not a dichotomous character (Haille- Selassie, Suwa, White). The fact that these hominids began to walk on two feet may be attributed to an increasing male role in carrying off spring as well as collecting food.
