The process of grooming and reciprocation fosters bonding between the individuals involved, regardless of whether the groomer benefits from a clear reciprocal response. Because allogrooming benefits each individual and engenders bonding between the individuals, it serves to facilitate and mediate social interactions within primate groups, which allows for successful group living, which entails large fitness benefits for group members.
As an additional or alternate explanation, it has also been hypothesized that at least some grooming is "truly altruistic" in that it does not confer a greater expected benefit than cost on the groomer.
According to this hypothesis, grooming behavior is selected for via kinship selection. This would mean that while allogrooming may not confer a fitness advantage to an individual, it would confer a fitness advantage to their family Schino, Since family members are more closely related, they share more genes with each other and hence by increasing each others' fitness, they increase the expected fitness of parts, at least, of their genome. Closer relatives do indeed spend more time grooming each other especially in the case between mothers and infants , so this hypothesis is supported somewhat by experimental evidence.

Social grooming is widespread among primates, where it serves a primarily social purpose, rather than a hygienic one Henzi and Barrett, Extensive studies have been conducted for the better understanding of the purpose behind this seemingly altruistic behavior, and our website will attempt to take a deeper look at the significance of the behavior from the biologist's perspective.
