Ardipithecus Ramidus Kadabba: The Oldest Hominid

There was a chief new discovery of fossil bones and teeth belonging to the earliest human ancestors ever discovered. The fossil bones predate the oldest formerly discovered human ancestor by more than a million years. The discovery was of fossil remains of a hominid that lived in present day Ethiopia between 5.2 and 9.8 million years ago. (Hominids include all species following the split as of the chimpanzees on the “human” side of the evolutionary tree.) “Analyses of the hominid indicate that they belonged to a previously unidentified species, which anthropologist Yohannes Haile-Selassie of the Cleveland Museum of Natural History and his colleagues are calling

Giday WoldeGabriel, a geologist with Los Alamos National Laboratory, and his colleagues, described the hominid’s environment in Africa. The creature lived during the Miocene era approximately 5 to 6 million years ago. Ardipithecus ramidus kadabba lived in a forested environment. The surroundings that he lived in were much different then the present are today; which include harsh deserts. When the hominids were living there the area was much cooler and more wet, also about 1,500 feet higher in elevation. Based on a toe bone discovered among other fossils belonging to this new hominid, it has been determined by Haile-Selassie that “Ardipithecus ramidus kadabba almost certainly walked on two legs when on the ground. The creature’s teeth share more characteristics with all later discovered hominids than with the teeth of all fossils and modern apes” (Rickman 2001). Ardipithecus ramidus kadabba ate a smaller amount of fruit and more soft leaves than prior chimpanzees, according to the fossils of the hominids relatively large back teeth and narrow front teeth. Finding Ardipithecus ramidus kadabba was a remarkable challenge. The present day Middle Awash area where the hominid was found is now covered with lakes, forest areas, volcanic rocks and sediments. Only one percent of the Middle Awash contains exposed ancient-sediments that contain mammal fossils. “The new
