Which of the following is true of age preferences in mate selection among humans?
As men age, the age difference between them and their wives increases.
Nearly all of the ethnographic data from cultural anthropology point to which conclusion?

Children who receive care from both parents are more likely to thrive.
What does Borgerhoff Mulder suggest may be the reason why there is no relationship between the wealth of the father of the groom and the bridewealth payment among Kipsigis?

How does evolutionary theory explain why chastity is considered essential in China but unimportant in Sweden?
Evolutionary theory cannot yet explain why chastity is considered essential in China but unimportant in Sweden.
To what extent can evolutionary theory currently explain human behavior?
Evolutionary theory provides insight into some behavioral traits, but there are other common behaviors that seem to contradict evolutionary logic.
Why might natural selection predispose women toward making more false negative errors when judging a partner's or potential partner's intentions?
Fear of becoming pregnant causes them to err on the side of caution about their partner's intentions.
Why did Borgerhoff Mulder find that bridewealth payments increased as the age of the bride at time of menarche decreased?
Greatest value was placed on the bride's reproductive potential.
Your friend wants to know why anthropologists interested in the human environment of evolutionary adaptedness are so intent on studying the food-gathering practices of hunter-gatherer societies. How do you reply?
Humans were foragers for the majority of our existence, and it is thought that our brains are adapted to life in foraging societies.
During Thanksgiving dinner, your uncle notes that first-cousin marriage is legal in many states. Your cousin is horrified, and your mom asks you if there is an anthropological reason that cousin marriage causes controversy. How do you reply?
