Australopithecus afarensis
Research history

In 1978, Johanson, Tim D. White and Coppens classified the hundreds of specimens collected thus far from both Hadar and Laetoli into a single new species, A. afarensis, and considered the apparently wide range of variation a result of sexual dimorphism. The species name honours the Afar Region of Ethiopia where the majority of the specimens had been recovered from. They later selected the jawbone LH 4 as the holotype specimen because of its preservation quality and because White had already fully described and illustrated it the year before.
