Canine sexual dimorphism is one particular type of sexual dimorphism, in which males of a species have larger canines than females. Within primates, the male and female canine tooth size varies among different taxonomic subgroups, yet canine dimorphism is most extensively found in catarrhines among haplorhine primates.
The teeth, both in absolute size and relative proportions, are the same as in gorillas, and the molars range in size between the largest and smallest of what is normally seen in adult gorillas. Like in gorillas, the upper molars have a long protocone crest, and the lower molars have a correspondingly long trigonid crest, which increase shearing ...

Additionally, adult males have sharp canine teeth. Like all great apes, it has a dental formula of 2.1.2.3 2.1.2.3, that is, two incisors, one canine, two premolars, and three molars on both halves of each jaw. Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [41]

Hair colors can change well into puberty, as some genes aren't "switched on" until the hormones flood the body in adolescence. Eventually, usually in the 30s, human hair stops producing melanin ...
Changes to the dental morphology and jaw are major elements of hominid evolution. These changes were driven by the types and processing of food eaten. The evolution of the jaw is thought to have facilitated encephalization, speech, and the formation of the uniquely human chin.
