You'll never guess who walked in!

Research output: Contribution to specialist publicationArticle


The international team of paleoanthropologists and paleontologists published their analyses of a hominin called Ardipithecus ramidus in the journal 'Science.' The closest representative of the species is a partial female skeleton nicknamed Ardi, who is 4.4 million years old. The naming of Ardi involved various complexities. The genus into which the type specimen of Ardipithecus was initially classified was Australopithecus. A brief corrigendum appeared in 'Nature,' revising the naming of the fossils from Australopithecus ramidus to Ardipithecus ramidus. Ardi was clearly not chimp, nor Lucy nor human. Paleoartist Jay Matternes reconstructed her as having fur everywhere but on the center of her face, which protruded more than expected for a hominin. The fur, the long arms and the divergent big toe give Ardi the gestalt of an odd chimp, but that bipedal gait transforms Ardi back into a hominin.
