Document Summary

If evolution has shaped the psychology of human mating strategies, then we would expect to find common patterns across societies. 3: a false negative occurs if you think the other person doesn"t like you, when they really do, both kinds of errors are costly. A false positive could lead you to make an overture that would be rejected. A false negative could prevent you from making any overture at all: pregnant women are expected to be cautious about their partner"s intentions and as a result, will make more false negative errors than false positive errors. They are likely to overestimate women"s sexual interest more often than underestimate it. Chastity is considered essential in china, but not in sweden: data suggests that human mate preferences are strongly influenced by the cultural and economic environment in which they live. Kipsigis bridewealth: evolutionary theory explains marriage patterns among the kipsigis, a group of east african pastoralists.

Best practice to participate in the discussion boards is to read the articles and consider the following questions. Then go to the discussion board and talk amongst yourselves; don't forget to post a minimum of a paragraph and reply to a colleague.

1. Some evolutionary psychologists, such as David Buss, suggest that men are more promiscuous than women. Man are hardwired for sex, wanting to have sex with as many women as possible. This is an evolutionary advantage, which gives men the opportunity to impregnate as many women as possible (i.e. to spread their seed). In addition, men prefer to have sex with women that are younger and have an hourglass shape. Both youth and a curvy figure are evolutionary signifiers of reproductive health. Buss also suggests that women are more selective in their mating and dating preferences. While men have a tendency to want to sleep around, women are choosier. Why? Because men have the ability to impregnate many women, while women can only have one offspring at a time. It is evolutionarily advantageous for women to be picky about their mates. What kind of mate to women prefer? They prefer mates with power and resources; men who can provide for the survival of their offspring. For our early ancestors this meant a man who could "bring home the bacon" now this means a man who brings home the money. Feminist evolutionary psychologists think this is just ridiculous. This type of thinking just portrays men and women as stereotypes.

2. Critics of the above theory demand: show me the physiological evidence. Evolutionary theory is rooted in biology hence there must be physical evidence to substantiate a claim. Feminist evolutionary psychologists say: It's not men who want sleep around, in fact, it is women who are hard-wired to want to take on as many mates as possible. This is why society has spent so much energy trying to regulate female sexuality. What is the evidence? One: only maternity is 100%. Everyone knows for certain the identity of their mother, yet before the recent advent of testing, paternity was never 100%. In a communal living situation, all the men in the tribe would have to provide for a child because the possibility could be that child was their own. Two: women are multi-orgasmic, while men only have one orgasm and then their brain releases a chemical which causes them to fall asleep. As many know, women become active post-coitus. They want to talk and cuddle, while men want to nap. The suggestion here is that while men are sleeping it off on the bear skin rug, the women go to the next tent and have sex again with someone else. Finally, women have an organ designed specifically for sexual pleasure: the clitori. Men do not have such an organ. The existence of the clitori is a strong physiological indicator that supports the above assertion. How can you explain the existence of the clitori?
