orrorin tugenensis
Fossils have been found at four sites (Cheboit, Kapsomin, Kapcheberek, and Aragai) in the Tugen Hills, Kenya. Reconstructing the physical environment in which our ancestors lived allows us to gain a greater understanding of their day-to-day lives.
The type specimen, BAR 1000’00, is a jaw fragment with three lower molars. The main similarity is that the Orrorin femur is morphologically closer to that of Homo sapiens than is Lucy's; there is, however, some debate over this point.
Orrorin tugenensis is a postulated early species of Homininae, estimated at 6.1 to 5.7 million years (Ma) and discovered in 2000. ramidus (5.8–4.4 mya), a primate from Aramis, central Ethiopia, and one of the two fossil species of Ardipithecus, was also bipedal.In this case the evidence comes from the foramen magnum, the hole… [3] As of 2007, 20 fossils of the species have been found. In this section, explore all the different ways you can be a part of the Museum's groundbreaking research, as well as come face-to-face with our dedicated staff. You have reached the end of the main content. [6], The fossils of Orrorin tugenensis share no derived features of hominoid great-ape relatives. [7] According to recent studies Orrorin tugenensis is a basal hominid that adapted an early form of bipedalism. The 20 fossils have been found at four sites in the Lukeino Formation, located in Kenya: of these, the fossils at Cheboit and Aragai are the oldest (6.1 Ma), while those in Kapsomin and Kapcheberek are found in the upper levels of the formation (5.7 Ma).

[7] The current prevailing theory is that Orrorin tugenensis is a basal hominin and that bipedalism developed early in the hominin clade and successfully evolved down the human evolutionary tree. Senut, B., Pickford, M., Gommery, D., Mein, P., Cheboi, K., Coppens, Y., 2001. Our species, Homo sapiens, has now spread to all parts of the world but it's generally believed that we originated in Africa by about 200,000 years ago. Humans are classified in the sub-group of primates known as the Great Apes. INTRODUCTION. The most important fossil of this species is an upper femur, showing evidence of bone buildup typical of a biped - so Orrorin tugenensis individuals climbed trees but also probably walked upright with two legs on the ground. Examining the skulls of living apes and our extinct ancestors allows us to explore characteristics which reflect the evolutionary relationships in our family tree. The remains include several limb bones, jaw fragments and isolated teeth. In human evolution: The fossil evidence …found in Kenya of six-million-year-old Orrorin tugenensis indicate to some experts that they too were bipeds.Ar. Important changes to the brain have been occurring for more than two million years. Since then, according to the Community Museums of Kenya chairman Eustace Kitonga, the fossils are stored at a secret bank vault in Nairobi. Current use of the term ‘hominid’ can be confusing because the definition of this word has changed over time. First hominid from the Miocene (Lukeino Formation, Kenya). Senut, Brigitte; Martin Pickford; Dominique Gommery; Pierre Mein; Kiptalam Cheboi; Yves Coppens (2001). [8] However the femora morphology of O. tugenensis shares many similarities with Australopithicine femora morphology, which weakens this claim. Science 319, 1662-1665.

The team that found these fossils in 2000 was led by Brigitte Senut and Martin Pickford[2] from the Muséum national d'histoire naturelle.

However, it may have used simple tools similar to those used by modern chimpanzees including: When this species lived, the environment was open woodland with dense tree forests. It is not confirmed how Orrorin is related to modern humans. ORRORIN TUGENENSIS: Genus: Orrorin: Species: Orrorin tugenensis: Other Names: Original Man, Millenium Man: Time Period: 6 to 5.8 million years ago: Characteristics: Its discovery was used to argue against the hypothesis that australopithecines are human ancestors, as much as it still remains the most prevalent hypothesis of human evolution as of 2012.

Claimed as one of the most significant discoveries in the field of human evolution, the fossils possibly represent the oldest known human ancestor after the split of the human line from that of the chimpanzees. 'Millennium ancestor', a 6-million-year-old bipedal hominid from Kenya. However, this is hotly debated. This website may contain names, images and voices of deceased Aboriginal and Torres Strait Islander peoples. A research team led by French paleontologist Brigitte Senut and French geologist Martin Pickford discovered this species in the Tugen Hills region of central Kenya.
