Chapter 4/5 Flashcards
problems faced by ancestral females
Parent investment: human offspring are dependent and vulnerable and require intense investment for a long period
Protection: protection from sexual coercion; protect offspring
Health: Healthy mate can invest more for longer, unhealthy mate source of infection, offspring will have good immune system
Female long-term preferences
paternal investment: resources (social status, older, good prosects), personality traits (ambitious & industrious, dependable & stable generous), love & commitment, likes children
protection: tall & musclar, athletic
health: attractiveness, masculinty
female preference for male body type
Prefer mesomorphs (muscular) > ectomorphs (skinny) > endomorphs (obese)
problems faced by ancestral males
female production: fertility, reproductive value
paternity uncertainity: cuckoldry (cost of investment is wasted, investment benefits a rivals genes)
competition for mate: some men cannot find partners, men can have children with mutliple partners, reproductive success is more variable in men
______: likelihood that copulation will lead to a viable pregnancy (peaks at 25)
fertility
_________ - average number of future offspring an individual can have (peaks during late teens in women)
reproductive value
male long-term preferences
female fertility & health - youthfulness, attractiveness, detecting ovulation
paternity uncertanity - fiathfulnes of partner, commitment from partner
reproductive variability - commitment of partner, desire for multiple partners
_________: (truncated development)
- ______ : later onset
- ______ : earlier offset
- ______ : reduced rate
paedomorphosis
- post-displacement
- progenesis
- neoteny
_________: (extended development)
- ______ : earlier onset
- ______ : later offset
- ______ : accelerated rate
peramorphosis
- pre-displacement
- hypermorphosis
- acceleration
Theory that states that homosexuaals might invest heavily in genetic relatives
kin altruism theory
Hypothesis that states female relatives of gay men produce more offspring than those of straight men
female fertility hypothesis
hypothesis that suggests that women seek mates with power, status and earning capacity due to thier exclusion from power and resoruce control; refuted by evidence that high earning women are even more choosy when it comes to resources
structural powerlessness
