Smaller cheek teeth (molars and premolars) than … Orrorin tugenensis is considered to be the second oldest - after Sahelanthropus - known hominin ancestor that is possibly related to modern humans, and it is the only species classified in genus Orrorin. In 2001 the fossilized remains of mankind’s earliest known ancestor, surpassing predating previous discoveries by more than 1.5million years, were discovered in East Africa. [9] These features are shared with many species of Australopithecus. "[8] It does, however, also share many of such properties with several Miocene ape species, even showing some transitional elements between basal apes like the Aegypropithecus and Australopithecus. [9] It has been suggested by Pickford that the many features Orrorin shares with modern humans show that it is more closely related to Homo sapiens than to Australopithecus. tugenensis femur differs from those of apes and Homo and most strongly resembles those of Australopithecus and Paranthropus, indicating that O. tugenensis … [1], The name of genus Orrorin (plural Orroriek) means "original man" in Tugen,[2][3] and the name of the only classified species, O. tugenensis, derives from Tugen Hills in Kenya, where the first fossil was found in 2000.

Thousands of vertebrate fossils have also been found at the site including elephants, giraffes, antelopes, hippopotamus, crocodiles, lizards, monkeys, fish and wild boar. While the proximal phalanx is curved, the distal pollical phalanx is of human proportions and has thus been associated with toolmaking, but should probably be associated with grasping abilities useful for tree-climbing in this context. Dr. Chris Stringer of the Natural History Museum said although there would be debate over whether Millennium Man lay on the evolutionary path to humans, chimpanzees, or is an evolutionary dead end, so few remains had come from this period that it would be significant in any event. Orrorin tugenensis. [8] This would mean that Australopithecus would represent a side branch in the homin evolution that does not directly lead to Homo. Diet: Herbivory and hard seeds in robust forms A bit more omnivory in gracile forms Tool use: Tools associated with Australopithecines. [8] In contrast, "Orrorin shares several apomorphic features with modern humans, as well as some with australopithecines, including the presence of an obturator externus groove, elongated femoral neck, anteriorly twisted head (posterior twist in Australopithecus), anteroposteriorly compressed femoral neck, asymmetric distribution of cortexin the femoral neck, shallow superior notch, and a well developed gluteal tuberosity which coalesces vertically with  the  crest  that  descends  the  femoral  shaft  poste-riorly. The dentition differs from both these species in the presence of a mesial groove on the upper canines. The average brain size is about 530 cc. But it is the teeth and jaw that most clearly links Millennium Man to modern humans, according to Dr. Brigitte Senut, a team member from the Museum of Natural History in Paris. It is at least six million years old, which means it is older than the [previously oldest] remains found at Aramis in Ethiopia, which were 4.5 million years old.”. Millennium Man, as the apeman was named, was unveiled by a team of French and Kenyan paleontologists from the Kenya Palaeontology Expedition, who had unearthed remains from at least five males and females. If Orrorin proves to be a direct human ancestor, then australopithecines such as Australopithecus afarensis ("Lucy") may be considered a side branch of the hominid family tree: Orrorin is both earlier, by almost 3 million years, and more similar to modern humans than is A. afarensis.
