Early hominid genus, arguably the earliest fossil since humans are separated from chimpanzees as far as their closest relatives still exist today. It is currently known that there are 2 species of this genus Ardipithecus can be roughly interpreted as 'ape living on the ground'.
Ardipithecus kadabba
His name means the 'oldest ancestor'. Known only from pieces of teeth, skull fragments and a number of other pieces. Tests showed originated from about 5.6 million years ago. Originally thought to be the ancestor of ramidus, but the Ethiopian tooth findings indicate they are a separate species.
Ardipithecus ramidus
Discovered in 1992-19993 by team-led archaeologist Tim D. White, and named A.ramidus in September 1994, ramidus is indicated to be about 4.4 million years old. Found in the Afar region, Etheiopia, in the form of skull pieces, teeth, arm bones and other pieces, originally suspected as Australopithecus. But then summed up as a separate genus. Another finding was found around 1999-2003, in the form of bones of about 9 A.ramidus.
The greatest finding of ramidus is a specimen which came to be known as Ardi (ARA-VP-6/500). female ramidus found in the Afar desert. This is one of the most complete fossils of fossils before australopithecines, encompassing skulls, teeth, bones of hands and feet (including fingers). Ardi's findings proved that Ardi is not a common ancestor of humans and chimpanzees, because Ardi's feet are better suited for walking (though they can not be used for walking away).
