The study is based on grooming activity in different age class members of Semnopithecus entellus entellus all-male bands (AMB). All males seem to reach a peak in grooming frequency during and immediately following puberty and it is suggested that this peak corresponds to a period of establishing coalition bonds. High grooming rates may also be found in young adults who are actively and assertively challenging higher-ranking individuals. Finally, some old males exhibit paternalistic behavior toward young (generally pre-pubertal) males, which includes grooming, co-feeding and active defense by the older male. These observations are consistent with the hypothesis than grooming is an instrumental behaviour analogous to human gift exchange, which can be “used†by an individual for his ultimate benefit.
