NationMaster - Encyclopedia: Australopithecus anamensis

Australopithecus anamensis is a fossil species of Australopithecus. The first discovery (a single arm bone) was made by a research team in 1965. Believed to be four million years old, very little was known about the finding until 1987 when Canadian archaeologist Allan Morton (with Harvard University's Koobi Fora Field School), discovered fragments of the specimen eroding from a hillside east of Allia Bay, near Lake Turkana, Kenya. Six years later British/Kenyan paleoanthropologist Meave Leakey and archaeologist, Alan Walker excavated the Allia Bay site and uncovered a few additional fragments of the hominid in the hot dusty terrain. The complete lower jaw found resembles that of a Common Chimpanzee (Pan troglodytes), but the teeth are definitely closer to those of Humans.

Although they did not find hips, feet or legs, Meave believes that Australopithecus anamensis often climbed trees. Tree climbing for early hominins remained one ape-like trait that passed on until the first Homo species appeared about 2.5 million years ago. A. anamensis shares many traits similar to Australopithecus afarensis and may as well be its direct predecessor. A. anamensis is thought to have lived from 4.4 and 3.9 million years ago, coincidently when A. afarensis appears in the fossil record. Its name is derived from anam which means "lake" in the local Turkana language.

The fossils (twenty one in total) include upper and lower jaws, cranial fragments, and the upper and lower parts of a leg bone (tibia). In addition to this, a fragment of humerus that was found thirty years ago at the same site at Kanapoi has now been assigned to this species. Figure 1 : Upper surface of right tibia. ...

In 2006, a new A. anamensis find was officially announced. The find was in an area known as Middle Awash, only six miles away from a find of the most modern species of Ardipithecus, called A. ramidus, and in the same area as more modern Australopithecus finds. Ardipithecus was a more primitive hominid, considered the next known step below Australopithecus on the evolutionary tree. The A. anamensis find is dated to about 4.2 million years ago, the A. ramidus find to 4.4 million years ago, placing only 200,000 years between the two species. Between them and the more modern Australopithecus finds, there is a remarkable chain of evidence of human evolution in a single place, almost as if one were looking at a scattering of generations in a single family line.^[1] The Middle Awash is an archaeological site along the Awash River in Ethiopias Afar Depression. ...
