Description: Australopithecus afarensis skull "Lucy", light finish, (3.2 million years).
The Australopithecus afarensis Skull "Lucy" was discovered by D. Johanson in 1974 in Hadar, Ethiopia. Several branches of the hominid evolutionary tree that began between 2 and 3 MYA stemmed from "Lucy's" species. Although the short stature of this female, only 107cm, suggests that she was immature, eruption of the third molar provides evidence that this specimen was mature, and was simply a female representative of a sexually dimorphic species. The jaw shares features with both apes and other early hominids, with the shape showing some similarities to apes, with relatively large front teeth and parallel-sided tooth rows, and the size of the canine teeth being intermediate between apes and hominids who lived later. The cheek teeth are intermediate in size between hominids who lived earlier and those who lived later. The brain of "Lucy" was relatively small and overlapped in size with living apes. However, the shape of the pelvis, along with other characteristics of the postcranial skeleton, indicates that "Lucy" walked upright. At the same time, other characteristics of the limb skeleton indicate that members of this species spent time in the trees. This combination of an ape-sized brain in a hominid adapted to upright walking adds to the evidence that bipedalism occurred before the development of a relatively large brain.

The Bone Clones® Hominid Series
Our aim is to provide the best possible facsimile models of the most important hominid finds for the general public, educators and students, using the best reference material available. Each hominid has been carefully researched and re-created based on some or all of the following: casts of original fossils, the latest literature (descriptions and/or published measurements), input from the scientific community and full colour, life-size photographs. Every effort has been made to accurately re-create anatomical details of colour, size, shape, reconstructed areas, and bone/fossil texture. The hominids offered in this series are high quality, artistic recreations that can be advantageously used by educators as important visual aids in the classroom and appreciated by the general public. They are not intended for advanced graduate work nor to be measured for research purposes.
