Term | Definition |
---|---|
consilient | agreement between the approaches to a topic of different academic subjects, especially science and the humanities. |
teleology | explanation of phenomena by the purpose they serve rather than by postulated causes |
male marriage commitment | more likely to attract mate, more desirable mate, child survival and success, social status, coalitional allies, increases paternity certainty |
women's ovulation | cryptic |
human sexual activity | occurs throughout women's ovulation cycle |
reproductive value | number of children a person of a given age is likely to have in the future |

youth and health | correlated to reproductive value |
mate preferences | intelligent, kind, understanding, healthy, shared values, and religious beliefs |
as men age | they prefer younger women and younger women (or rather more reproductive value or fertility) |
male teens willing to accept dates (contrary to learning theory) | from older women (even though older women weren't interested in them and they could control younger easier) |
that older men desire increasingly younger women and teens prefer older non-interested women | only explained by the evolutionary time link between youth and fertility |
older men do not prefer most fertile women becuase | difficult to attract, less compatibility, more need for compatibility now than in hunter-gatherer times |
spousal age difference predicts | mate homicide rate |
male standards of female beauty | reproductive cues: physical appearance and behavior |
female reproductive cues: physical appearance | full lips, clear, smooth skin, clear eyes, long lustrous hair, good muscle tone, body fat distribution |

US men selected | exactly average female slimness |
US women selected | slimmer than average |
hip and thigh fat | 40% greater for post pubescent women that men making female WHR lower for women (.67-.80) than men (.85-.95) |
women with lower WHR | show earlier pubertal endocrine activity |
regardless of fat men favor | a WHR of .7(beauty contest winners and centerfold women) and women .8 |
