Australopithecus boisei skull, female (1.7 million years).
Female. The Australopithecus boisei skull KNM ER 732 was discovered in 1970 at Koobi Fora, Kenya by R. Leakey and H. Mutua and described in Nature in 1971. A comparative analysis of KNM ER 732 and KNM ER 406 revealed a host of similarities with the only differences (e.g., smaller size, lack of sagittal and nuchal crests in KNM ER 732) being typical of the sexual dimorphism found in great ape skulls. Consequently, KNM ER 732 is considered to be a female and KNM ER 406 a male of the species, Australopithecus boisei. Using the sexual dimorphism found in this pair as a guide, researchers suggested that A. robustus and A. africanus, which had been hypothesized by some to be male and female specimens of the same species, were, in fact, far more different than one would expect from simple sexual dimorphism. They proposed instead that A. robustus and A. africanus were separate species.

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.
