Akber Malik Einstein’s Universe NYT #3 NYT: Fossil Skeleton From Africa Predates Lucy Scientists found fragments of an extremely old hominid back in 1992, but just this week were able to present a fairly complete skeleton and an analysis of it. It is the oldest known skeleton from the human branch of the primate family tree, replacing Lucy, which was thought to be the oldest. Lucy, a member of the species Australopithecus afarensis, is 3.2 million years old, while Ardi, the name for this newfound specimin of the species Ardipithecus ramidus, is 4.4 million years old. The discovery of Ardi helps scientists learn more about the origins of our own species by looking at the earliest possible evolutionary steps after the chimpanzee. Ardi stood roughly four feet tall and weighed in the vicinity of 120 pounds, which is roughly a foot taller and double the weight of Lucy. Scientists both involved in the research and

Ardi was found 45 miles south of where Lucy was found 35 years ago in Ethiopia. The first bit of Ardi that was uncovered was just a molar found in 1992, but over the years more and more of her was found. Examination of the 145 teeth found suggest that Ardi was omnivorous, eating plants and nuts and small mammals, but they didn’t eat fruit like living gorillas and chimpanzees. One of the main disputes surrounding Ardi is whether or not she walked upright or not. Respected experts all over the world disagree on this. Regardless, it is a very significant step. In elementary school and middle school, I was always taught about Lucy and how important that find was; now, textbooks will have to replace a few paragraphs and talk about Ardi....
