American Association for the Advancement of Science (AAAS) in October 2009 announced the discovery of history and type Ardi, who had been studied since 1994, the discovery in Ethiopia Ardi suspected based on hoard soil layer was derived from 4.4 million years ago. This means that Ardi shifted pre-human fossil known Australopithecus afarensis, or the so-called Lucy (found in 1974 only 74 km from the discovery Ardi), which is estimated from 3.2 million years ago – the closest fossil species of human ancestors.

What you see is the result of engineering and sketches JK Matternes with reference to the detailed records and engineering experts that the most scientific approach of the results of scientific research for 15 years. Visualization is based on the discovery of hominid bones with the weight of a woman with 50 pounds of high-120cm.

The experts gave the name Ardi – an abbreviation of Ardipithecus ramidus – the most complete specimens of Ardipithecus ramidus 35 hominid fossils have been discovered. Ardipithecus ramidus name comes from a traditional Greek sufix preceded by the words in the local Afar language in which Ardi means ‘land’ and ramid means ‘root’ which berarrti ‘root of the ground ape’ or ‘root of the monkeys the mainland’.

The researchers very carefully up from a number like 125 bones in the picture above. Tim White who led the Human Evolution Research Center at the University of California states: “To understand biology, the parts that you want there is a skull and teeth, pinggu arms and hands and feet. And we have all. “

The discovery of fossil remains of Ardipithecus ramidus occurred in 1992 in northern Ethiopia. While the discovery of a complete Ardi above is the year 1994 in the village of Aramis.

Ardi fossil discoveries seem to be a fossil of an important missing link that can fill the ‘gaps’ in scientific knowledge about the evolution of primates before the skulls ‘Lucy’ Australopithecus afarensis, but after the hominid line split from the line leading to modern chimpanzees and to open a window on human evolution very little we know.

Experts say that Ardi evolsionari not in the direct line of human origin, but the ancestors of humans, how we evolved from the same ancestor that humans have with apes, bonobos, gorillas and other primates high level.

This is not Aripithecus chimpanzees and not human. Ardi able to work well with both feet on the reconstruction of the most scientific and most likely, although still with a bent posture. When climbing with legs and arms, Ardi not use his knuckles like the monkey or gorilla, but with the palm of his hand. “There is no current monkey who uses his palm.”

C. Owen Lovejoy said, “We can not be a blessing that this is soesies direct ancestor of modern humans, so we must be careful. Ardi but this shows us that the early hominids are far from chimpanzees. ”

Ardi discovery has made a textbook on human origins have to be rewritten.

Tim White said, “People think that modern chimps have not changed and so, our ancestors looked like a chimp … as if a chimpanzee is the only branch of human beings evolved. In fact, Ardi is the more primitive (older) than in chimpanzees.

Although the findings in the area of triangle Ardi Afar – Ethiopia today is the wilderness, scientists have discovered that the wood had become fossilized, and the seeds of plants are also beside the bones of Ardipithecus ramidus and concluded that 4.4 million years ago where it was forest type.
