Ardipithecus ramidus is a species of australopithecine from the Afar region of Early Pliocene Ethiopia 4.4 million years ago (mya). A. ramidus , unlike modern hominids , has adaptations for both walking on two legs ( bipedality ) and life in the trees ( arboreality ).
Ardipithecus is a genus of an extinct hominine that lived during the Late Miocene and Early Pliocene epochs in the Afar Depression, Ethiopia.Originally described as one of the earliest ancestors of humans after they diverged from the chimpanzees, the relation of this genus to human ancestors and whether it is a hominin is now a matter of debate.

Ardi (ARA-VP-6/500) is the designation of the fossilized skeletal remains of an Ardipithecus ramidus, thought to be an early human-like female anthropoid 4.4 million years old. It is the most complete early hominid specimen, with most of the skull, teeth, pelvis, hands and feet, [ 1 ] more complete than the previously known Australopithecus ...
Tim D. White (born August 24, 1950) is an American paleoanthropologist and Professor of Integrative Biology at the University of California, Berkeley.He is best known for leading the team which discovered Ardi, the type specimen of Ardipithecus ramidus, a 4.4 million-year-old likely human ancestor.
This model is supported by the reduction ("feminization") of the male canine teeth in early hominids such as Sahelanthropus tchadensis [71] and Ardipithecus ramidus, [72] which along with low body size dimorphism in Ardipithecus [73] and Australopithecus, [74] [75] [76] suggests a reduction in inter-male antagonistic behavior in early hominids ...
The australopithecines, formally Australopithecina or Hominina, are generally any species in the related genera of Australopithecus and Paranthropus.It may also include members of Kenyanthropus, [4] Ardipithecus, [4] and Praeanthropus. [5]
Dated to live around 5.6 to 4.4 million years ago. Fossils show Ardipithecus to have canine teeth that were reduced, much like later hominids. The jaw of Ardipithecus was very much prognathic. [6] The teeth of Ardipithecus ramidus in particular showed that the species was probably an omnivore
In 1993, 4.4 million year old fossil teeth were found in Aramis, Ethiopia, by a group led by Tim D. White attributed to a new species, Australopithecus ramidus, later called Ardipithecus ramidus. The age was thus half a million years older than previously known A. afarensis and had a more monkey-like appearance. [24]
