Ardipithecus. 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 ...
Ardipithecus ramidus. 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). However, it would not have been as efficient at bipedality as ...
Australopithecus is a member of the subtribe Australopithecina, [4][5] which sometimes also includes Ardipithecus, [6] though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali and A. deyiremeda.
Australopithecine. 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] The term comes from a former classification as members of a distinct subfamily, the ...
Ardipithecus most likely appeared after the human-chimpanzee split, some 5.5 million years ago, at a time when gene flow may still have been ongoing. It has several shared characteristics with chimpanzees, but due to its fossil incompleteness and the proximity to the human-chimpanzee split, the exact position of Ardipithecus in the fossil ...
Successive dispersals of Homo erectus (yellow), Homo neanderthalensis (ochre) and Homo sapiens (red), with the numbers of years since they appeared.. Several expansions of populations of archaic humans (genus Homo) out of Africa and throughout Eurasia took place in the course of the Lower Paleolithic, and into the beginning Middle Paleolithic, between about 2.1 million and 0.2 million years ...
Ardi. 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 ...
Australopithecus anamensis is the intermediate species between Ardipithecus ramidus and Australopithecus afarensis and has multiple shared traits with humans and other apes. [30] [8] Fossil studies of the wrist morphology of A. anamensis have suggested knuckle-walking, which is a derived trait shared with other African apes.
