Ontogeny in the Family

Abstract: When ontogeny takes place in a family, and parents provide essential resources for development, the parents become an environmental component to the development of a wide range of offspring traits. Because differences among parents may partly reflect genetic variation, this environmental component contains genes and may itself evolve. Also, when offspring play an active role in family interactions, offspring become a social environmental component to parents, affecting their behavior in turn, which potentially… Show more

“…Carotenoids could therefore also mediate the covariation between parental and offspring behaviour. Our experiments suggest that variation among families in offspring solicitation intensity, and covariation within families between parent and offspring behaviour, is not solely the result of genetic variation (see Kö lliker 2005;Dor & Lotem 2009). Our feeding experiment suggests that it partly results from the wider environmental conditions experienced by mothers (and fathers) during nesting and egg laying (see also Kölliker et al 2000;Moreno et al 2008).…”

“…Animal families have become model systems for understanding how the social environment influences the course of evolution (see Trivers 1974;Godfray 1995a;Mock & Parker 1997;Moore et al 1997;Kö lliker 2005;Uller 2008;Zeh & Zeh 2008). Traits of particular interest are the solicitation behaviours performed by dependent young as they demand resources and the provisioning behaviour shown by parents in response.…”

“…That interest has come from a number of perspectives. Some of us (e.g., Alleva et al, 1989;Ko¨lliker, 2005;Mandillo and D'Amato, 1997) are like Crowcroft, interested in the ethology and ecology of such interactions. Some (e.g., Ryan and Vandenbergh, 2002) are interested in the effects of early hormone exposure on pups and the effects of those exposures on subsequent physiology and behavior.…”

“…Selection acting at the level of the individual primarily favours large, well-nourished offspring, as might be expected, whereas selection acting at the level of the family depends upon how gregarious offspring are (SNS) in relation to the size of the network (brood) involved. Variation in social network attributes [35] or traits correlated with SNS, such as begging intensity or parental feeding behaviour, can be heritable [19,23,36,37]. If, as seems probable, SNS has a heritable basis, then family structure can evolve.…”

“…SNS can affect average group performance so it can shape the structure of social interactions within groups, and, therefore, social evolution [1,2,10,14,41], including the evolution of family life [19]. Further work is needed to determine causality in the relationship between parent-offspring interactions and brood SNS, and the mechanistic basis of the effect of nestling SNS on recruitment probability.…”
