Ardipithecus kadabba is known to have a canine that sharpens itself against the first premolar, a trait that is considered indicative of its placement within the hominin family. This characteristic is not attributed to Sahelanthropus tchadensis, Orrorin tugenensis, or Ardipithecus ramidus in the same context.
