Canine tip wear in male and female anthropoids.
One component of the "dual selection hypothesis" (Greenfield [1992a] Year. Phys. Anthropol. 35:153-185) is that the tips of female canines are commonly blunted and more frequently so than those of conspecific males. Data derived from two randomly selected age-graded samples of Macaca fascicularis (n = 70) and Colobus badius (n = 59) show that at least 80% of the females exhibit tip blunting on one or both canines and that frequencies of blunting are far greater than those of conspecific males in both jaws. Sexual dimorphism in mandibular canine morphology and wear and other recently critiqued aspects of the "dual selection hypothesis" (Plavcan and Kelley [1996] Am. J. Phys. Anthropol. 99:379-387.) are also discussed.
