How are Australopithecus anamensis similar to Ardipithecus ramidus?
Tooth size variability in A. anamensis suggests that there was significant body size variation. In relation to their diet, A. anamensis has similarities with their predecessor Ardipithecus ramidus. A. anamensis sometimes had much larger canines than later Australopithecus species.
How are australopithecines related to modern apes?
