摘要

Behavioural ecology is the study of how natural selection shapes behaviour in relation to ecological and social conditions. A fundamental principle is that individuals should promote the spread of their own genes over those of competitors. For example, adults sacrifice themselves to defend and nourish offspring. But they try to avoid providing assistance to non-relatives (that is, they avoid 'misdirecting' their nepotism), usually by guarding their mate against other sexual liaisons and attempting to distinguish their own offspring from unrelated young. Mistakes in discrimination are most likely for males of internally fertilizing species, especially when the females accept multiple partners. Indeed, in most such species males do not care for young, and it has been suggested that this is because they are uncertain which juveniles are their own. But a new study by Buchan and colleagues, described on page 179 of this issue, reveals that when male savannah baboons (Papio cynocephalus) intervene in fights between juveniles, they favour offspring over non-kin. This work is important because it reveals that such intervention is a manifestation of nepotism, that paternal care can occur even when females copulate with several different males, and that the kin-recognition mechanisms of a wild primate approach those of humans in precision and sophistication.
