The name of genus Orrorin (plural Orroriek) means "original man" in Tugen, and the name of the only classified species, O. tugenensis, derives from Tugen Hills in Kenya, where the first fossil was found in 2000. The postcanines (the teeth behind the canines) were relatively large, and had more enamel compared to contemporary apes and humans . They date to between 6.1 and 5.8 mya and are therefore of Miocene age. Orrorin tugenensis 1) Found by Brigitte Senet and Martin Pickford 2) Located near Lake Turkana and dated to 6 mya .

Our brains have increased in size more than four-fold, from a more chimp-sized brain (<400 cc) in the earliest hominins to a mean of ~1400 cc. At an age of 6 million years, it could be one of the first hominids living after their split from lineages leading to other great apes. Brain size of 530 cc iv.

O. tugenensis was discovered by Brigitte Senut and Martin Pickford in 2001 in the Tugen hills of Kenya. Bipedalism, however, appears to have been established in the six-million-year-old Orrorin tugenensis, . Orrorin tugenensis is significant in the origins of human evolution because it can be classified as an early bipedal hominin. However, in most other respects, including brain size, it is apelike. This species lived sometime between 7 and 6 million years ago in West-Central Africa (Chad). This likely occurred in response to environmental stresses as well as competition with other hominins for resources. number of fossil examples average capacity of the braincase (cc) Australopithecus: 6: 440: Paranthropus: 4: 519: Homo habilis: 4: 640: Javanese Homo erectus (Trinil and Sangiran) . .

Other characteristics, like the massiveness of the face, jaws and single tooth found, and the largest sagittal crest in any known hominid, are more reminiscent of A. boisei (Leakey and Lewin 1992). The two dashed lines signify important thresholds in the phase transition from Life evolution into Cultural evolution. The founding research team claims that features of the femur indicate that Orrorin was a biped and in the direct line to modern humans. Sahelanthropus tchadensis; Graecopithecus.

Homo helmei was 'beetle-browed' [sullen or unfriendly in appearance], the same size as us, and with an average brain volume slightly larger than ours at 1,400 cm 3. Orrorin tugenensis is remarkable because, despite being older than the australopithecines, it appears to have a closer resemblance to humans than later species such as Australopithecus afarensis (which is best known for the famous fossil "Lucy").
