  • Beschreibung: <jats:p> Late Miocene fossil hominid teeth recovered from Ethiopia's Middle Awash are assigned to <jats:italic>Ardipithecus kadabba</jats:italic> . Their primitive morphology and wear pattern demonstrate that <jats:italic>A. kadabba</jats:italic> is distinct from <jats:italic>Ardipithecus ramidus</jats:italic> . These fossils suggest that the last common ancestor of apes and humans had a functionally honing canine–third premolar complex. Comparison with teeth of <jats:italic>Sahelanthropus</jats:italic> and <jats:italic>Orrorin</jats:italic> , the two other named late Miocene hominid genera, implies that these putative taxa are very similar to <jats:italic>A. kadabba</jats:italic> . It is therefore premature to posit extensive late Miocene hominid diversity on the basis of currently available samples. </jats:p>
