They had a brain size similar to that of chimps, between 300 and 350cc. De tanden lijken wat op die van Australopithecus. Ardipithecus leefde 4,4 miljoen jaar geleden in het vroege Plioceen.. Er zijn twee soorten beschreven: Ardipithecus ramidus en Ardipithecus kadabba.De laatste was aanvankelijk beschreven als ondersoort van Ardipithecus ramidus … Ardipithecus ramidus skull According to Evolutionists , ardipithecus ramidus is an example of the earliest known hominins , a group whose members include humans and their ancestors, which Anthropologists believe is roughly 4.4 million years old. The fossil find was dated on the basis of its stratigraphic position between two volcanic strata. As such, it has a mix of ape-like and hominin characteristics. 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 and life in the trees (arboreality).However, it would not have been as efficient at bipedality as humans, nor arboreality as non-human great apes. Ardipithecus is een uitgestorven zeer vroeg geslacht van de geslachtengroep Hominini, waar de mens toe behoort. The Ardipithecus ramidus Skull and Its Implications for Hominid Origins Gen Suwa,1* Berhane Asfaw,2 Reiko T. Kono,3 Daisuke Kubo,4 C. Owen Lovejoy,5 Tim D. White6 The highly fragmented and distorted skull of the adult skeleton ARA-VP-6/500 includes most of the Group of Ardipithecus ramidus skull and postcranials. The species dates to several million years after the split between hominins and chimps (approximately 7.5-9.5mya). Ardipithecus ramidus lived approximately 4.4 million years ago in Ethiopia. Ardipithecus ramidus and the evolution of the human cranial base. Its short posterior cranial base differs from that of both Pan troglodytes and P. paniscus . Ardipithecus ramidus, nicknamed in 1994 'Ardi' (meaning 'ground' or 'root'), lived about 4.4 million years ago during the early Pliocene. If this option is enabled, an exact search will be performed and similar words will not be searched. The Ardipithecus ramidus skull exhibits a small endocranial capacity (300 to 350 cubic centimeters), small cranial size relative to body size, considerable midfacial projection, and a lack of modern African ape–like extreme lower facial prognathism.
