Human: Phylogeny

1.6 MYA. This Homo ergaster femur was one of the skeletal elements discovered in 1984 in Nariokotome, Kenya by Richard Leakey (and described as H. erectus). The discovery of the many skeletal parts gave anthropologists a great deal of information regarding body size, limb proportions, locomotion and age of death (11 to 12 years old). The elongated neck of the femur is typical of australopithecines. This femur comes from the skeleton KNM-WT 15000, SC-012.
