Showing one's teeth, in primates, is considered a submissive gesture.
"Monogamy" (pair bonding and sharing domestic/offspring-related duties) in primates is not to be confused with sexual fidelity, which is rare.
Primates have advanced cognitive abilities: some make tools and use them to acquire food and for social displays; some have sophisticated hunting strategies requiring cooperation, influence and rank.
Some primates engage in predation of other primates and eat them.
