PSY E112 Lecture Notes - Lecture 20: Parental Investment, Inclusive Fitness, Limiting Factor
Document Summary
Related to reproductive and survival success in ancestral environments. Much past evidence for evolution was found in maladaptive traits. To determine recent natural selection look at organisms with short lifespans (can study genes that have undergone recent selection; ex. Adaptations contributed (historically) to reproductive successes (fitness) of individuals or to repro. Success of individuals and their relatives (inclusive fitness) Daly/wilson theory- evolution designed people to desire things and experience. Long-term relationships serve social affiliation and child-rearing functions that emotions that increased their fitness in ancestral environments enhance reproductive success. Behavioural genetic studies look at degree to which diff"s among people are attributed to genetic influence (not species-typical genetically caused traits) Male sexual interest to signs of female reproduction capability adaptation partners. Maximizes attraction to and motivates behaviour toward reproductively capable. Related to reproductive and survival success in ancestral environment (men with system were likely to out-reproduce men w/o it) Parental investment- energy, time, resources and cost associated w/ producing.
