A. kadabba is considered to have been the direct ancestor of A. ramidus, making Ardipithecus a chronospecies. [7] The exact affinities of Ardipithecus have been debated. White, in 1994, considered A. ramidus to have been more closely related to humans than chimpanzees, though noting it to be the most ape-like fossil hominin to date. [1]
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.

Aramis is a village and archaeological site in north-eastern Ethiopia, where remains of Australopithecus and Ardipithecus (Ardipithecus ramidus) have been found.The village is located in Administrative Zone 5 of the Afar Region, which is part of the Afar Sultanate of Dawe, with a latitude and longitude of , and is part of the (Daale Faage Woreda), Carri Rasuk, Xaale Faagê Daqaara
Ardi's foot is a special area of interest when examining the evolution of bipedalism in early Hominids, and the bipedality of Ardipithecus ramidus, because all five toes do not line up. [17] The remains of the foot from Ardi and other Ardipithecus ramidus specimens that can be studied includes "a talus, medial and intermediate cuneiforms ...
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]
The chimpanzee–human divergence likely took place around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.
Discovery of Ardipithecus kadabba (2004) 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.
