“…if they expect that their latest brood is more highly related to them than average they will care more. Westneat and Sherman (1993) come to a similar conclusion and furthermore argue that given the expected relationship of two males to their partner's present brood is equal to their average relationship, then those two males should give the same level of paternal care, even if one male is on average more related to the offspring of his partner than the other. Houston and McNamara (2002) argue that the model of Westneat and Sherman is inconsistent and that the level of male care must depend on the average level of relationship of a male to his partner's brood.…”

A LARGE POPULATION PARENTAL CARE GAME: POLYMORPHISMS AND FEEDBACK BETWEEN PATTERNS OF CARE AND THE OPERATIONAL SEX RATIO DAVID M. RAMSEYAbstract. This article presents a game theoretic model of parental care which models the feedback between patterns of care and the operational sex ratio. It is assumed here that males can be in one of two states: searching for a mate or breeding (including caring for their offspring).Females can be in one of three states: receptive (searching), non-receptive or breeding. However, these sets of states can be adapted to the physiology of a particular species. The length of time an individual remains in the breeding state depends on the level of care an individual gives.When in the searching state, individuals find partners at a rate dependent on the proportion of members of the opposite sex searching. These rates are defined to satisfy the Fisher condition that the total number of offspring of males equals the total number of offspring of females.The operational sex ratio is not defined exogenously, but can be derived from the adult sex ratio and the pattern of parental care. Pure strategy profiles and so called single sex stable polymorphisms, in which behaviour is varied within one sex, are derived analytically. The difference between mixed evolutionarily stable strategies and stable polymorphisms within this framework is highlighted. The effect of various physiological and demographic parameters on patterns of care are considered.

“…Obligate investment means that male care is necessary for the survival of his offspring. In these species, selection will favor males who invest in offspring and could eventually result in males showing high levels of paternal investment, independent of proximate conditions (Westneat & Sherman, 1993).…”

“…Human paternal investment and that of many other species is facultatively expressed, that is, it is not always necessary for offspring survival and thus can vary with proximate conditions (Westneat & Sherman, 1993). The facultative expression of paternal investment is typically found when there is a high degree of paternity certainty; when investment improves offspring survival rates; and, when it does not severely restrict opportunities to mate with multiple females (Birkhead & Møller, 1996;Møller & Cuervo, 2000;Perrone & Zaret, 1988;Trivers, 1972).…”

Male parental investment is unusual in mammals, occurring in less than 5% of species, including humans. The chapter reviews the cost–benefit trade‐offs that likely contributed to the evolution and maintenance of human paternal investment and the proximate mechanisms that influence individual differences in the expression of this investment. The latter include biological (e.g., hormones), social (e.g., quality of the marital relationship), and wider cultural (e.g., rules for polygynous marriages) mechanisms.

“…Studies conducted on a wide range of species support the hypothesis that parenting evolved because the accompanying behaviors -providing food and protection from predators -covary with the likelihood that offspring will survive to adulthood (Clutton-Brock, 1991;Krebs & Davies, 1993;Trivers, 1972Trivers, , 1974Westneat & Sherman, 1993;Williams, 1966;Wolf, Ketterson, & Nolan, 1988). The same theoretical model and assumptions (e.g., the importance of calories) often guide the study of human parental behavior and family formation in preindustrial societies and the construction of models of their evolution (e.g., Hill & Hurtado, 1996;Lovejoy, 1981;Wrangham, Holland Jones, Laden, Pilbeam, & Conklin-Brittain, 1999).…”

SYNOPSISObjective. To develop an evolutionary model that integrates human parenting and family formation with ideas about the evolved functions of distinctive human characteristics, such as concealed ovulation and sophisticated sociocognitive competencies. Design. Theoretical and empirical research across scientific disciplines is reviewed. The emphasis is on ecological and social conditions that covary, across species, with parenting, family formation, and potentially coevolving characteristics, such as a long developmental period. Results. For humans, social competition through coalition formation emerges as the key selective pressure that readily explains the coevolution of a constellation of characteristics that covary with parenting and family formation, including a lengthy developmental period, reduced sexual dimorphism, concealed ovulation, menopause, complex kinship networks, large brains, and sophisticated sociocognitive competencies. Individual and cross-cultural variations in patterns of parenting dynamics and family formation are viewed as adaptive phenotypic responses to different ecological and historical conditions. Conclusions. Human parenting and family formation are features of a coevolving suite of distinctive human characteristics, the evolutionary function of which is to facilitate the formation of kin-based coalitions for competition with other coalitions for resource control. In this view, a central function of human parenting and the human family is to provide a context for the development of sociocompetitive competencies appropriate to the local ecology.
