What a pity it would have been if biologists had refused to accept Darwin's theory of natural selection, which has been essential in helping biologists understand a wide range of phenomena in many animal species. These days, to study any animal species while refusing to consider the evolved adaptive significance of their behavior would be considered pure folly--unless, of course, the species is homo sapiens. Graduate students training to study this particular primate species may never take a single course in evolutionary theory, although they may take two undergraduate and up to four graduate

Using a method developed in previous field studies of aggression, this study examined the influence of ambient temperature on responses to a car stopped at a green light. To investigate alternative models of the effects of high temperature on interpersonal hostility, the study was conducted during the spring and summer in Phoenix, Arizona, and included a range on the temperaturehumidity discomfort index up to 1 160. Results indicated a direct linear increase in horn honking with increasing temperature. Stronger results were obtained by examining only those subjects who had their windows rolled down (and presumably did not have air conditioners operating).

Is a man's sexual peak earlier than a woman's? Three studies were conducted to examine (a) whether the perception that men achieve their sexual peak at a younger age than do women is shared across individuals of different ages and sexes, (b) whether sexual peak is defined differently for men and women, and (c) whether differences between definitions contribute to differences in the age at which men and women are perceived to reach sexual peak. Study 1 suggested that participants believed that females reach their sexual peak at an older age than do males. Study 2 indicated that the defining feature of sexual peak for males was sexual desire and for females was sexual satisfaction. Study 3 suggested that predictions of male sexual peak coincided with participants' predictions of male age of highest desire and frequency, but not satisfaction, and that female sexual peak coincided with participants' predictions of female age of highest satisfaction but not frequency or desire. Discussion focuses on potential reasons for differences between the perception of male and female sexuality, as well as the social and evolutionary importance of each of the dimensions of sexuality for both males and females.

The present study investigated mate preferences for five different levels of relationship involvement—marriage, serious relationship, falling in love, casual sex, and sexual fantasies–among individuals of 20, 30, 40, 50, and 60 years of age. Consistent with an evolutionary perspective, men preferred mates who were higher in physical attractiveness than themselves, whereas women preferred mates who were higher in income, education, self–confidence, intelligence, dominance, and social position than themselves. The lower the level of relationship involvement, the lower were the preferred levels of education, physical attractiveness, and, particularly for males, preferred intelligence in comparison to oneself. For sexual fantasies, men and women preferred mates who were higher in physical attractiveness than those they preferred for real partners. There were few age differences in mate preferences, although older individuals set higher standards for a potential mate's education.
