Document Summary
Pscyh 110 book notes chapter 3: genetics and evolutionary foundations of behavior. Review of basic genetics mechanisms: how genes affect behavior, how genes are passed along in sexual reproduction. Inheritance of behavioral traits: single-gene inheritance, polygenic characteristics and selective breeding, epigenetics. Evolution by natural selection: darwin"s insight: selective breeding occurs in nature, genetic diversity provides the material for natural selection, environmental change provides the material for natural selection, evolution has no foresight. Natural selection as a foundation for functionalism: distal and proximate explanations of behavior, limitations on functionalist thinking. Natural selection as a foundation for understanding species-typical behavior: species-typical behaviors in humans, the value of cross-species comparisons of species-typical behavior. Evolutionary analysis of hurting and helping: sex differences in aggression, patterns of helping, final words of caution: 2 fallacies to avoid. Humans and chimpanzees share 98. 8% of dna. Adaption modification as a result of changed life circumstances: evolution is a long-term adaptive process.
