She was a fossil dated at about 3.2 million years. Anita Schiller, Director of the Biocontrol Mosquito Initiative in Harris County Precinct 4 is working with our staff to test an innovative, eco-friendly way to control the population of mosquitoes in Harris Country using a natural predator of everybody’s least favorite insect called the mosquito assassin […], The world is a vast place, but all life living on its surface sprung from the same origins. Move Over, Lucy; Ardi May Be Oldest Human Ancestor Scientists working in Ethiopia have discovered what they say is the biggest trove of fossils yet … Standing 120 centimeters tall, Ardi had a body and brain only slightly larger than a chimpanzee's, and she was far more primitive than Lucy. She is 4.4 million years old. The fossil remains of Ardi were found just 74 kilometres from where those of Lucy were found in 1974. After all the evidence that many anthropologist, archeologist, and paleoanthropologist discovered and examined to prove that Lucy and Ardi’s ability to walk upright is clear that they are ancestors in our human evolutionary tree. The discovery of the genus Ardipithecus and the study of the environment in which they once lived have caused us to revisit and refine the thinking on the origins of upright walking. Especially when it comes to supposed “ape-men” like Lucy, Ardi, and others, we must be aware of the fact that evolutionary ideas may be (consciously or subconsciously) guiding the reconstruction. Two fossils named Ardi and Lucy provide evidence for human evolution. More Information on Lucy What is important about Lucy? Learn how your comment data is processed. After their discovery of the first Ardipithecus remains in 1992, scientists had identified the bones of 17 hominid fossils by the end of 1993. Who was Ardipithecus? Ardi, an adult female, probably stood four feet tall and weighed about 120 pounds, almost a foot taller and twice the weight of Lucy. Over a period of several years, the team followed up with more excavations at the location of the original discovery. One significant feature about Ardi was that she was also bipedal. Scientists rely on an equally extensive array of approaches to find answers. Among living non-human primates, researchers have observed bipedal stances in creatures such as orangutans as they move around in the trees, while chimpanzees most often stand upright when they feed on small objects in the trees. Predictably, creationist outlets use the sentiment that Ardi has overturned our understanding of human evolution to make their point that scientists “do not agree” when it comes to human evolution. However, we can’t be sure that bipedalism first emerged in the Awash Valley. With. Lucy was a more adept upright walker than Ardi. Illustration of Ardi by paleoartist Elisabeth Daynes In regards to the skeletal reconstruction of Lucy, the 3.2 million-year-old Australopithecus, Jerry Coyne observed: “Lucy had a very apelike head with a chimp-sized braincase… One could not ask for a better transitional form between humans and ancient apes than Lucy. It seems that Ardi was equally at home on the ground as she was in the trees. Wij hebben Ardi, en zij is maar liefst 1,2 miljoen jaar ouder dan Lucy. This evidence has caused a re-examination of the hypothesis on the origin of upright walking. The climate was cool and wet. The story of human history continues to evolve, and Ardi tells us even more about the distant human past. Creatures adapted to living in trees were now forced to cross grasslands in order to go from one island of trees to another, the thinking went. Lets start with the first question: who was Ardipithecus? There is more than one species within the genus Ardipithecus. The remains of Ardipithecus kadabba and Ardipithecus ramidus have been found in Eastern Ethiopia. While Lucy is the most famous Hominid, her cousin “Ardi” (Ardipithecus ramidus), at 4.4-million-years-old, became the oldest when he was discovered in 1992. While Ardi’s canines were smaller than those of chimpanzees and gorillas, Lucy’s canines were even smaller in comparison. Ardi's biggest surprise is that she was not transitional between Australopithecus and a common ancestor that looked like living chimpanzees and gorillas. Required fields are marked *. Ardipithecus, the earliest known genus of the zoological family Hominidae (the group that includes humans and excludes great apes) and the likely ancestor of Australopithecus, a group closely related to and often considered ancestral to modern human beings. It began as a small, “softball-sized” colony that now has grown many times […], 5555 Hermann Park Dr. Their brain size was similar to that of a chimp. This is not the first time that a celebrated fossil of an early hominid species had been discovered in Ethiopia as the very important Lucy fossil, of an individual from a species known to science as Australopithecus afarensis and dating from some 3.2 million years ago, was unearthed in 1974 only 74 kilometres from where the fossil remains of Ardi were found. This is an extensive array of questions, not unusual to find when fossils are discovered. Being an omnivore is another trait that sets, , underscoring the great interest in the study of human origins. Armin van Buuren - Control Freak (Sander van Doorn Extended Remix).mp3 - 16.83 MB 016. Ardi and Lucy were discovered in Ethiopia(Afar). Ardi was 1.2 million years older than lucy, was also female and belonged to the species Ardipithecus ramidus.
