Parental Investment by Sex on Ifaluk
نویسندگان
چکیده
Trivers and Willard (Science 179:90-92, 1973) predict that where investment by parents in good condition increases the fitness of sons more than that of their sisters, while the opposite is true of parents in poor condition, parents with much to invest will favor sons, while those with little will favor daughters. Patterns of parent-child association on Ifaluk atoll are consistent with this prediction.

Sex differences in parental care: Gametic investment, sexual selection, and social environment.
Male and female parents often provide different type and amount of care to their offspring. Three major drivers have been proposed to explain parental sex roles: (1) differential gametic investment by males and females that precipitates into sex difference in care, (2) different intensity of sexual selection acting on males and females, and (3) biased social environment that facilitates the mor...
متن کاملSex-biased immunity is driven by relative differences in reproductive investment.
Sex differences in immunity are often observed, with males generally having a weaker immune system than females. However, recent data in a sex-role-reversed species in which females compete to mate with males suggest that sexually competitive females have a weaker immune response. These findings support the hypothesis that sexual dimorphism in immunity has evolved in response to sex-specific fi...
متن کاملParental investment in Tibetan populations does not reflect stated cultural norms
In this paper, we examined both stated norms of sex preference and actual sex-biases in parental investment in a Tibetan pastoralist society. We collected detailed demographic data on infant mortality, infant feeding, the length of interbirth intervals, and a decision when giving gifts, to examine sex-biased parental investment. Our results indicate a mismatch between self-reported son preferen...
متن کاملThe evolution of parental care in the context of sexual selection: a critical reassessment of parental investment theory.
Males and females are often defined by differences in their energetic investment in gametes. In most sexual species, females produce few large ova, whereas males produce many tiny sperm. This difference in initial parental investment is presumed to exert a fundamental influence on sex differences in mating and parental behavior, resulting in a taxonomic bias toward parental care in females and ...
متن کاملP Parental Investment Theory ( Middle - Level Theory in Evolutionary Psychology )
Parental investment is referred to as any expenditure (time, energy, resources, etc.) that a parent incurs to benefit an offspring. Parental investment theories in evolutionary biology and evolutionary psychology explore mechanisms underlying parent-offspring relationships and investment. These theories examine adaptive functions and fitness dynamics of parent-offspring relationship, and how en...
