In biology, sociology, and biological anthropology, alloparenting is a system of parenting in which individuals other than the parents act in a parental role. One common form of alloparenting is a situation in which grandparents adopt a parental role. This is sometimes named a "skipped generation household". In 1997, 8% of children in the United States lived with their grandparents, with the grandparents being the caregivers in one third of those cases. According to Deihl, the Efé people of Ituri Forest in the Democratic Republic of Congo practice alloparenting, with care for infants coming from siblings, grandparents, and older members of the community. Deihl states that where siblings are alloparents this provides adolescents experience of being a parent, and that similar practice in the United States would reduce the rate of teenage pregnancy and make teenage parents "better parent() when they do become parents." In biology, "Cooperatively breeding vertebrate systems are characterized by individual ‘helpers’ that take care of young ones within the social group that are not their own offspring — a behaviour termed ‘alloparental care’." In mammals, care typically encompasses allolactation, pup-feeding, babysitting and carrying young." An example of is when male Barbary macaques carry around unrelated infants and care for them for hours at a time.〔Small, Meredith F. "Alloparental Behaviour in Barbary Macaques, Macaca Sylvanus." ''Animal Behaviour'' 39.2 (1990): 297-306 〕 Another example is when warthog sows suckle piglets from other litters after the sows have lost their own litters.〔Jensen, S.P., Siefert, L., Okori, J.J.L., Clutlon-Brock, T.H. (1999). "Age Related Participation in Allosucking by Nursing Warthogs." ''Journal of Zoology'' London 248(4): 443–449〕 In some fishes such as redlip blennies, males perform alloparental care. ==See also== * Sarah Blaffer Hrdy * Cooperative breeding 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alloparenting」の詳細全文を読む スポンサード リンク
