Penemu Ardipithecus Ramidus

Penemu Ardipithecus Ramidus. Ardipithecus ramidus Ardipithecus ramidus is a species of australopithecine from the Afar region of Early Pliocene Ethiopia 44 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 humans nor at arboreality as nonhuman great apes Species †A ramidusGenus †Family Kingdom.

Important Fossil DiscoveriesWhat The Name MeansDistributionRelationships with Other SpeciesKey Physical FeaturesCultureEnvironment and DietHundreds of pieces of fossilised bone were recovered during 19921994 all from localities west of the Awash River in Aramis Ethiopia The finds number over 110 specimens and represent about 35 individual members of this species Most of the remains are dental but some skull and limb bones were also found A partial humerus (arm bone) indicates that this species was smaller than the average Australopithecus afarensis In 2005 the remains of 9 individuals were recovered from As Duma in northern Ethiopia The remains mostly consist of teeth and jaw fragments but also some bones from the hands and feet Some specimens discovered earlier in Kanapoi Lothagam and Tabarin could also belong to this species Key specimens 1 ARAVP6/1 teeth This is the holotype for this species It consists of teeth and jaw bone and was found in Aramis in 1993 2 &#39Ardi&#39 ARAVP6/500 A partial skeleton found in 1994 consisting of about 125 pieces was described and published in 2009 It is the olde The name is derived from the local Afar language ‘Ardi’ means ‘ground’ or ‘floor’ and ‘pithecus’ is Latinised Greek for ‘ape’ The name ‘ramid’ means ‘root’ in the Afar language Fossils belonging to this species were found in eastern Africa in the Middle Awash valley Ethiopia Additional fossils that may also belong to this species have been collected in northern Kenya This species position as a direct ancestor of humans is unclear and scientists are still debating where it should be placed relative to our direct line The discovers think it was ancestral to Australopithecus it is the only putative hominin in evidence between 58 and 44 million years ago but others do not agree Even if Ardipithecus ramidus isnot on our direct line it must have been closely related to the direct ancestor and probably similar in appearance and adaptation It also offers new insights into how we evolved from the common ancestor we share with chimps This species was originally classified as Australopithecus ramidus in 1994 but was reclassified in 1995 because its discoverers believed it was distinct enough to be placed into a new genus Ardipithecus This species was a facultative biped and stood upright on the ground but could move on all four limbs in trees Features of the anatomy are extremely primitive Brain 1 about 300350cc similar in size to modern female chimpanzees and bonobos Body size and shape 1 similar in size to modern chimpanzees The most complete specimen a female stood about 120cm tall 2 males were only slightly larger than females 3 the body shape was more apelike than humans but differed from living African apes in a number of significant features Limbs 1 mix of primitive and derived features suggest this species was able to walk upright on the ground yet efficiently climb trees 2 long powerful arms that were not used for weightbearing or knucklewalking as with quadrupedal apes 3 bones in the wrist (particularly the midcarpal joint) provided flexibility and the palm bones were short These features suggest this species was not a knucklewalker and that the palms could support the body weight w There is no evidence for any specific cultural attributes but they may have used simple tools similar to those used by modern chimpanzees including 1 twigs sticks and other plant materials that were easily shaped or modified These may have been used for a variety of simple tasks including obtaining food 2 unmodified stones that is stones that were not shaped or altered before being used These tools may have been used to process hard foods such as nuts Associated animal and plant fossils indicate this species lived a in relatively moist and heavily forested woodland Fossil species include plants such as fig palm and hackberry and animals like colobine and baboonlike monkeys kudu peafowl bats shrews rodents doves eagles owls and parrots The species with its apelike feet probably spent considerable time in the trees looking for food and shelter Diet may have included nuts fruit leaves tubers insects and small mammals They were probably more omnivorous than chimps (based on the size shape and enamel of the teeth) and fed both in trees and on the ground The evidence is inconclusive but studies suggest the front teeth were regularly used for clamping and pulling possibly reflecting a diet that included large amounts of leaves Tooth enamel analysis suggests they ate fruit nuts and leaves Carbonisotope studies of teeth show they ate woodland rather than grassland plants.

Ardipithecus ramidus; four feet to two – Naturally Inspiring

Ardipithecus is an early hominin known from Ethiopia Africa This group existed from about 58 to 44 million years ago The betterknown species of that group Ardipithecus ramidus is dated to 44 million years ago This species was bipedal but still relied heavily on life in the trees.
