1. Research demonstrates that girls who grow up in a home without a father present are more likely to experience early menarche compared with girls who spend their early childhood years with their father in the house. A) From the perspective of Life History Theory, for what basic fitness-relevant tasks do organisms face tradeoffs in terms of energy allocation? In order for any organisms to reproduce, effort must be apportioned among three fundamental tasks such as growth and development, mating, and parenting. B) According to Life History Theory, how does the presence or absence of a father in a human female's early developmental environment provide information relevant to this tradeoff? Evolution has designed humans to very there mating and child-rearing behavior in accordance with the contextual conditions in which they develop, so as to maximize their reproductive success. The presence or absence of father early developmental environment to induce in the child an understanding of the availability and predictability of resources in the environment, of the trustworthiness of others, and of the enduringness of close interpersonal relationships, all of which affect how the developing person apportions reproductive effort. C) Provide an additional empirical finding regarding the behavioral differences, on average, between human females who grow up in father-present vs father-absent homes. Provide an ultimate explanation for this finding, in terms of Life History Theory. Females who grow up in father-present tend to perceive others as untrustworthy, relationships as opportunities and self-serving, and resources as scarce and/or unpredictable will develop behavior patterns that functions to reduce the age of biological maturation, accelerate sexual activities, and short-term pair bond. Contrary, females who grow up in father-absence tend to perceive others as trustworthy. Relationships as enduring and mutually rewarding, and resources as more available from the same key persons, late age maturations, defer sexual activities, and long-term pair bond. D) Provide an alternative ultimate explanation for the correlation between father presence and age of menarche that does not follow from Life History Theory. An alternative, though not necessarily mutually exclusive, approach involves more of a cumulative conditional
