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 ).
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 ...
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. [1]
Ethiopia is considered the area from which anatomically modern humans emerged. [1] Archeological discoveries in the country's sites have garnered specific fossil evidence of early human succession, including the hominins Australopithecus afarensis (3.2 million years ago) and Ardipithecus ramidus (4.4 million years ago).
Ardipithecus Ardipithecus is, or may be, a very early hominin genus (tribe Hominini and subtribe Hominina). Two species are described in the literature: A. ramidus, which lived about 4.4 million years ago [32] during the early Pliocene, and A. kadabba, dated to approximately 5.6 million years ago [33] (late Miocene).
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]
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.
