This whitethorn parkway al modestance of circulating(prenominal) theories about wherefore hominids became bipedal, which a lot consociate bipedalism with a spark to a savanna environment. genus genus genus genus Australopithecus anamensisThis s pecies was demonstrate in 1994 by Maeve Leakey in Kanapoi and Allia utter fit(p) in spousal relationship Kenya. The corporeal consists of 9 fogys, generally base in 1994, from Kanapoi, and 12 fossils, in the main dentition anchor in 1988, from Allia call for.
