Ar·di·pith·e·cus

 (är′dĭ-pĭth′ĭ-kəs)
n.
A genus of extinct hominins known from fossil remains found in eastern Africa and dating from about 5.8 to 4.4 million years ago. Ardipithecus is widely considered to be ancestral to Australopithecus.

[New Latin Ardipithēcus, genus name : Afar (language of the area of Ethiopia where remains of the hominins were found) ardi, earth, ground (from Arabic 'arḍ; see ʔrṣ́ in Semitic roots) + Greek pithēkos, ape (of unknown origin).]

Ardi (for Ardipithecus ramidus, another species of hominid) was found in Ethiopia in 1994 and is believed to be around 4.5 million years old.
Some characteristics were shared with later species, while others had more in common with those of even older and more primitive early human ancestor groups such as Ardipithecus and Sahelanthropus.
However, scientists say the primitive cranial morphology links this fossil to even more ancient hominins, such as Sahelanthropus and Ardipithecus, and casts doubt on previous assumptions about a direct link to the younger Australopithecus afarensis.
In fact, the loss of megaherbivores begins 4.6 million years ago, a time when the only known hominin is Ardipithecus -- a small-brained and ape-like human ancestor that lacked stone tools and at best hunted small prey like modern-day chimpanzees.
Unfortunately, even the major Arabic language media at times interpret new scientific discoveries as discrediting Darwin, as happened in a posting on al-Jazeera reporting on the early hominid known as Ardipithecus (al-Jazeera, 2009).

More recent finds of Ardipithecus, an early hominin have led Lovejoy (2009) to effectively recast similar claims about a role of male provisioning and a sexual division of labor originating around five million years ago in Africa.
