The time primates spend grooming increases with group size, but too-large group sizes can lead to decreased group cohesion because time spent grooming is usually impacted by other factors, which include ecological, phylogenetic, and life history.
Grooming in primates meets the conditions for reciprocal altruism according to some studies. One of the studies in vervet monkeys shows that among unrelated individuals, grooming induce higher chance of attending to each other's calls for aid.

The first evidence of apparently arbitrary traditions came in the late-1970s, also in the behavior of primates. At this time, researchers McGrew and Tutin found a social grooming handclasp behavior to be prevalent in a certain troop of chimpanzees in Tanzania, but not found in other groups nearby. [7]
