Document Summary
Biology: cheetahs- run 70 mph> needed to chase prey, peacock- sexual selection> females have certain pref, perception, cognition, social cognition. Symmetry of a face- visual hues to evaluate attractiveness: most likely to have kids. Why men prefer youth: mutation> prefer older, lower chance of having kids, lower chance of gene passed to next generation, genes for preferring youth spread to next generation, natural selection. Selection pressures on wome: more resources, better chance of success in raising kids, male fertility declines little w/ age, environment of evolutionary adaptiveness, pleistocene: 2. 588 million bp to 12,000 bp. Iq decreases w/ birth order: natural selection for gf fat, fetal & infant neurodevelop, "hot"= better infant brain. What is the relationship b/w biology & conscious experience. Brains are the de facto casual basis of consciousness, no understanding whatever of how this can be so. Idealism: all is mental (consciousness is just perceptions in consciousness)
