By analogy from the pygmy chimpanzee, a species that shows considerable male-female overlap in canine dimensions (Almquist, 1974; Johanson, 1974) and is very similar in combined-sex coefficients of variation to A. afarensis, it can be inferred that males and females of A. afarensis most likely also overlap in canine dimensions.
