Allomothering, allomaternal infant care/handling, or non-maternal infant care/handling is performed by any group member other than the mother. Alloparental care is provided by group members other than the genetic father or the mother and thus is distinguished from parental care. Both are widespread phenomena among social insects, birds and mammals.
Allomothering, or allomaternal care, is parental care provided by group members other than the genetic mother. This is a common feature of many cooperative breeding species, including some mammal, bird and insect species. Allomothering in humans is universal, but the members who participate in allomothering vary from culture to culture.
The co-operative behaviour of social insects like the honey bee can be explained by kin selection.. Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. [1]
It is a key example of where the evolution has been driven by the combination of life history traits and ecological factors, which act as the triggers. [20] The first hypothesis put forward for the evolution of cooperative breeding was that a shortage of suitable breeding habitat encouraged young to remain at the nest or territory for a period ...
Sexual selection is an evolutionary concept that has been used to explain why, in some species, male and female individuals behave differently in selecting mates. In 1930, Ronald Fisher wrote The Genetical Theory of Natural Selection, [3] in which he introduced the modern concept of parental investment, introduced the sexy son hypothesis, and introduced Fisher's principle.
Greater likelihood of recalling recent, nearby, or otherwise immediately available examples, and the imputation of importance to those examples over others. Bizarreness effect: Bizarre material is better remembered than common material. Boundary extension: Remembering the background of an image as being larger or more expansive than the ...
In all of the above examples that are argued to support the 'nurture kinship' perspective, alternative interpretations may be equally persuasive or more insightful. In many such small communities, which may be isolated (such as the ones of the Chuuk of Micronesia), the relatedness between members of a group is to be assumed.
Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. [1] Bronfenbrenner developed the foundations of the theory throughout his career, [2] published a major statement of the theory in American Psychologist, [3] articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of ...
