Ardipithecus Ramidus Assignment Ardipithecus Ramidus is a genus of extinct hominids, identified from skeletal remains in the Northeastern Ethiopia, which has some form of a grasping big toe, and capable of some an upright. Evolution is various ways by which different organisms improve or develop from their former state. A fossil any remain or form of a prehistoric organism, which is preserved in a petrified form as a mold or cast in rock. (Correspondent)
After the discovery of the remains of Aridipithecs Ramidus, it is believed that human beings are an evolved version of it. It is the oldest species that possesses features that show a link to the human lineage. That means that it is very vital in terms of understanding human evolution, when it comes to what has changed or what hasn’t. (Correspondent)
The first report on Ardipithecus Ramidus was made in 1994. In 2009, scientists gave another report of a partial skeleton, which was nicknamed ‘Ardi’. The pelvis was constructed from a crushed specimen and showed adaptations that combine tree-climbing and bipedal activity. With the skeleton, the discoverers argue that the ‘Ardi’ reflects a human-African ape common ancestor that was not chimpanzee-like. (Correspondent)
The discoverers argue that the ‘Ardi’ skeleton reflects a human-African ape common ancestor that was not chimpanzee-like. A good sample of canine teeth of this species indicates a very little difference in size between males and females. The fossils were found alongside faunal remains, which suggests that she lived in a wooded environment. That, however, contradicts the open savanna theory, which suggests that humans learned to walk upright as climates became drier and environments became more open or grassy. Ardipithecus Ramidus Assignment
The first team that discovered Ardipithecus Ramidus were led by American paleoanthropologist, Tim White. They found the fossils in the Middle Awash area of Ethiopia between 1992 and 1994. Since then, the team has uncovered over 100 fossil specimens of Ar. Ramidus. The reason they chose that name for the fossil is that ‘ramid’ means root in Ethiopian language, and they had seen the closeness of the new discovery to the roots of humanity. (Report)
Important fossil discoveries. Ardipithecus Ramidus Assignment
During 1992-1994, there were hundreds of pieces of fossilized bones that were recovered. All of them were from the Awash River, in Aramis, Ethiopia. The said number represents about 35 individual members of the species. Most of the remains were dental, but some skull and limb bones were also found. A partial humerus, (arm bone) indicates that this species was smaller than the average Australopithecus afarensis, which had been discovered a bit earlier. Later on in 2005, there were more remains of 9 individuals that were discovered from As Duma in northern Ethiopia. These mostly consisted of teeth and jaw fragment, but also some bones from the hands and feet.
Key specimens. Ardipithecus Ramidus Assignment
• ARA-VP-6/1 teeth.
That being the holotype for that particular species, consisted of teeth and jaw bone, and was found in Aramis in the year 1993.
• ‘Ardi’ ARA-VP-6/500.
That was discovered in 1994. It was a partial skeleton consisting of about 125 pieces and was described and published in 2009. It is the oldest known skeleton of a human ancestor. The individual is believed to be a female and is nicknamed ‘Ardi.’ She weighed about 50kg and stood about 120 cm tall. Due to the extremely poor condition, the skeleton was found in, it took the team 15 years to excavate, scan, make virtual reconstructions, assemble and then analyze.
