Allomaternal care is a type of caregiving behavior that involves individuals other than the biological mother providing care and assistance to offspring. This can include fathers, siblings, other relatives, or even unrelated individuals within a social group. Allomaternal care is observed in various animal species, including primates, birds, and mammals, and can take many forms such as nursing, grooming, protection, and provision of food. Research on allomaternal care explores the factors that influence the extent and effectiveness of caregiving by non-parental individuals, as well as the impact of this care on offspring development, survival, and reproductive success. This research helps us better understand the evolution of social behavior, the dynamics of social relationships within a group, and the adaptive benefits of cooperative caregiving strategies.
