Ardipithecus Ramidus

Ardipithecus the earliest known genus of the zoological family hominidae the group that includes humans and excludes great apes and the likely ancestor of australopithecus a group closely related to and often considered ancestral to modern human beings.

Ardipithecus ramidus. The anatomy of ar. The pliocene 4 4 ma hominoid species ardipithecus ramidus has been linked phylogenetically to the australopithecus homo clade by nonhoning canines a short basicranium and postcranial features related to bipedality. It has been described as a probable chronospecies i e. Ramidus is best understood by examining ardi the partial skeleton found at aramis.

Because shares certain characteristics with apes some experts think it s an ancestor of chimpanzees instead of humans. It also offers new insights into how we evolved from the common ancestor we share with chimps. The pelvis reconstructed from a crushed specimen is said to show adaptations that combine tree climbing and bipedal. 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 at arboreality as non human great apes.

Ardipithecus ramidus was first reported in 1994. The foot bones in this skeleton indicate a divergent large toe combined with a rigid foot it s still unclear what this means concerning bipedal behavior. Ardipithecus ramidus is a species of australopithecine from the afar region of early pliocene ethiopia 4 4 million years ago mya. Ramidus in 2004 anthropologists yohannes haile selassie gen suwa and tim d.

Ardipithecus lived between 5 8 million. However aspects of the foot and pelvis indicative of arboreal locomotion have raised arguments that this taxon may instead exemplify parallel evolution of human like traits. This specimen preserves key details of the dentition skull forearm pelvis leg and foot of a young adult female. Ardipithecus adalah genus hominin yang hidup sekitar 4 4 juta tahun yang lalu selama zaman pliosen dua spesies pada genus ini telah dideskripsikan yaitu ardipithecus ramidus dan ardipithecus kadabba.

Between apes and australopithecines. Although originally considered a subspecies of a. In 2009 scientists announced a partial skeleton nicknamed ardi. Even if ardipithecus ramidus is not on our direct line it must have been closely related to the direct ancestor and probably similar in appearance and adaptation.

White published an article elevating a. Ardi presents a unique anatomical mosaic not previously observed in any other. The fossil find was dated on the basis of its stratigraphic position between two volcanic strata. Ramidus date to around 4 4 mya and show a mixture of ape like and australopithecine like features.
