	Ardipithecus ramidus
		Ardipithecus ramidus is the earliest hominid found so far and was discovered in Aramis, in the Middle Awash region of Ethiopia in 1994 by Tim White and his two colleagues, Gen Suwa and Berhane Asfaw.
		Ardipithecus ramidus translates literally as "ground man-root" and is thought to be 4.4 to 4.5 million years old.
		The dentition of Ardipithecus ramidus is more primitive (more apelike) than that seen in Australopithecus afarensis, with narrower molar teeth capped with thin enamel, unlike the condition in all other known hominines; the canines are larger, but not as large as in living apes.

	Ardipithecus ramidus
		They proposed Ardipithecus (from "ardi", which means "ground" or "floor" in the Afar language) to be the genus [White, et al, 1995].
		A morphological description of the initial, mainly dental, fossil remains of Ardipithecus ramidus was published by White et al, 1994.
		The length (in the mesiodistal plane) to breadth (in the buccolingual plane) ratio, which is roughly equal to 1 in later hominids, is much greater in A. ramidus.

		Because Ardipithecus ramidus was supposed to be a forest dweller, it might throw the most popular theory of the origin of hominid bipedalism out of favor, that hominids adapted to bipedalism to see across the grasses of the savannah.

	Earliest hominid discovery not the missing link — But close
		While Ardipithecus ramidus kadabba is not the sought-after "Missing Link"—the yet-undiscovered creature that lived at the cusp of the evolutionary division between man and chimp—Yohannes Haile-Selassie, a doctoral candidate at the University of California at Berkeley, said the hominid certainly is very close to the branching point.
		Because neither the skull nor intact limb bones of Ardipithecus ramidus kadabba have been found, however, an artists' rendition of the creature is impossible at this time.
		The new Ardipithecus subspecies fossils were tiny nuggets in a huge landscape littered with pebbles and boulders.

	Hominid fossils from Ethiopia link ape-men to more distant human ancestors
		More primitive hominids in the genus Ardipithecus date from between 4.4 million and 7 million years ago and were much more ape-like, though they, too, walked on two legs.
		Ardipithecus, on the other hand, was discovered by White and his team in 1992, based on fossils from Aramis, a village in the Awash Valley of Ethiopia's Afar rift.
		The teeth of Ardipithecus were smaller, restricting it to a diet of softer, less abrasive food, White said.

	Fossils of Oldest Human Ancestor in Ethiopia
		The Ethiopian creature, dubbed Ardipithecus ramidus kadabba, "rootman ancestor," walked upright - a classic characteristic separating humans from apes - and had teeth that appeared to be evolving from apes to human ancestors.
		The new Ardipithecus remains were found at 3,000 feet altitude, but the region was possibly much higher-perhaps 7,000 feet - and much greener 5.5 million years ago, with large lakes, forests and plenty of rain, and full of the resources that forest apes required to survive.
		It is probable that these Ardipithecus ramidus kadabba were tree dwellers who needed to come down to the ground so they could walk to the next tree.

	Ardipithecus Finds in Ethiopia
		Professor Tim White, of the University of California, Berkeley, agreed it was becoming apparent that Ardipithecus ramidus was an important species that was a very plausible ancestor to later hominids.
		Ardipithecus could therefore represent an earlier step on the path which led to modern humans, as well as a number of other, extinct hominid species.
		The age of the newly described remains was estimated by dating volcanic material found in their vicinity.

		Ardipithecus ramidus is considered to be the earliest member of the Hominoidea family, this is because it is the most ape-like hominid known.
		Ardipithecus ramidus is dated to about 4.4 million years ago, and displays a combination of human-like and chimp-like features.
		Third the arm structure of Ardipithecus ramidus is an intermediate between the great apes and later members of the hominid line.

	Ardipithecus - Wikipedia, the free encyclopedia
		Ardipithecus is a very early hominin genus (subfamily Homininae).
		Because it shares several traits with the African great apes (genus Pan and genus Gorilla), it is considered by some to be on the chimpanzee rather than human branch, but most consider it a proto-human because of a likeness in teeth with Australopithecus.
		ramidus suggests that the creature walked upright, and this poses problems for current theories of the origins of hominid bipedalism: Ardipithecus is believed to have lived in shady forests rather than on the savannah, where the more energy efficient locomotion permitted by bipedalism would have been an advantage.

		In a normal chewing stroke, the chimp's third premolar would rub against the back and inside of the upper canine, sharpening the edge on the upper canine and smoothly polishing the outer surface of the lower third premolar.
		When first reported in the journal Nature in 2001, the hominid was named Ardipithecus ramidus kadabba, a subspecies of a younger hominid, Ardipithecus ramidus, also from the Middle Awash region of Ethiopia.
		"Ardipithecus kadabba may also represent the first species on the human branch of the family tree just after the evolutionary split between lines leading to modern chimpanzees and humans," said Yohannes Haile-Selassie, curator and head of physical anthropology at the Cleveland museum.

		Ardipithecus ramidus is also marked out by its diamond-shaped upper canine teeth, which are more humanlike than the "V" shaped upper canines of chimpanzees.
		Another Ardipithecus species, kadabba, lived in Ethiopia at around 5.54 to 5.77 million years ago.
		But the authors add that it is not clear exactly in what sort of habitat the hominids lived.

		"Ardipithecus was close [in time] to the common ancestor of chimpanzees and humans," Haile-Selassie says.
		When Ardipithecus lived there, the region contained a dense forest and had a cool, wet climate, according to studies led by Giday WoldeGabriel of Los Alamos (N.M.) National Laboratory.
		Yet Ardipithecus lived in shady forests where a hominid would have less need to stand up to dissipate heat or walk long distances.

		In a 2001 publication in the journal Nature, the bones and teeth were first placed in a new hominid subspecies named Ardipithecus ramidus kadabba.
		In the 2002 field season, the scientific team recovered new fossil teeth of Ardipithecus kadabba at a place known as Asa Koma ("Red Hill") along the western margin of the Middle Awash study area, about 180 miles (290 km) northeast of the Ethiopian capital, Addis Ababa.
		On the phylogenetic relationship of Ardipithecus kadabba with the two other known genera of late Miocene hominids, Orrorin and Sahelanthropus, Haile-Selassie and his colleagues state that the three are similar to such an extent that they might belong to a single genus.

	John Hawks Anthropology Weblog : A ladder, not a bush?
		In addition to the paper, there are articles in the New York Times (by John Noble Wilford), the Associated Press (by Seth Borenstein), and BBC (by Paul Rincon).
		Tim D. White, a paleontologist at the University of California, Berkeley, who was a leader of the team, and his colleagues said the 4.1-million-year-old fossils were anatomically intermediate between the earlier species Ardipithecus ramidus and the later species Australopithecus afarensis, the Lucy family.
		This latter alternative is the only "bushy" interpretation -- the idea that known species of Ardipithecus can't really be the direct ancestors of Australopithecus, but that there must be some as-yet-undiscovered hominid (or better yet, hominids) that are the common ancestors, cousins, and other bushy relatives of the known species.

	El Defensor Chieftain: Tech scientist helps date fossils of early walkers
		The scientists found 30 bones that appear to be from nine separate individuals of a creature called "Ardipithecus ramidus," which lived in what is now Ethiopia, one of the cradles of human evolution.
		To pin down when Ardipithecus ramidus lived, a sample of basalt the size of a golf ball, found in a layer adjacent to where the bones were found, was brought to McIntosh's Socorro lab, where he analyzed potassium and argon in the rock to determine its age.
		Other fossils from the Ardipithecus family have been found in woodland settings, according to Semaw, but there is evidence for grasslands in the area where the new fossils were found.

		Their forebears -- possibly direct ancestors of Australopithecus -- are the Ardipithecus genus, which ranged across the entire continent as early as 6 million years ago.
		Ardipithecus became extinct about the time that the earliest of seven known species of Australopithecus emerged, the fossil record indicates.
		WoldeGabriel said petrified wood and the fossil bones of monkeys, kudus and other horned mammals among the hominids all indicate that the region was heavily forested during the time that Ardipithecus and the early Australopithecus species existed.

		By speaking of the 5.8 million years old Ardipithecus ramidus kadabba and the 6 million years old Orrorin tugenensis fossils as hominid, he portrays these finds as if evidence for evolution.
		The evolutionist claims about the Ardipithecus ramidus kadabba fossil had made the cover of the Time magazine but soon thereafter these claims were disproved by renowned scientist John Mastropaolo's detailed analysis.
		Some 95% of the skeleton was missing, yet evolutionists were still able to come up with the totally unrealistic idea that it could supposedly be seen from this toe that this creature was capable of walking on two legs, which shows in turn that man and apes evolved from a common ancestor.
