Document Summary

Occurs whenever these three things exist: ge(cid:374)e(cid:396)atio(cid:374) of di(cid:448)e(cid:396)sity. Survival and reproduction of the fittest: t(cid:396)a(cid:374)s(cid:373)itted (cid:272)ha(cid:374)ge. Biological evolution: natural selection, sexual selection, artificial selection (e. g. , breeding) O(cid:396)igi(cid:374)ally, the (cid:862)typi(cid:272)al(cid:863) (cid:373)oth (cid:894)(cid:396)ight(cid:895) flou(cid:396)ished i(cid:374) e(cid:374)gla(cid:374)d, (cid:271)e(cid:272)ause it (cid:271)le(cid:374)ded i(cid:374) (cid:449)ith the lichens on trees. During the industrial revolution, the trees became covered with soot, resulting i(cid:374) the flou(cid:396)ishi(cid:374)g of the da(cid:396)ke(cid:396) (cid:862)(cid:272)a(cid:396)(cid:271)o(cid:374) a(cid:396)ia(cid:863) (cid:894)left(cid:895). Whe(cid:374) e(cid:374)gla(cid:374)d (cid:272)lea(cid:374)ed itself up, (cid:862)typi(cid:272)al(cid:863) made a comeback. Evolutionary psychology: explaining psychological traits as evolutionary adaptations, adaptationism: theorizing about evolutionary causes for phenotypes, evolutionary psychology generates hypotheses, but these must be tested, many people will believe an evolutionary story without evidence. Predetermination: mostly i(cid:374)depe(cid:374)de(cid:374)t of e(cid:374)(cid:448)i(cid:396)o(cid:374)(cid:373)e(cid:374)t (cid:894)e. g. , eye (cid:272)olou(cid:396)(cid:895) They are useful for females but only constitute a minor nutritive cost for males. Exaptation: o(cid:373)ethi(cid:374)g e(cid:448)olved for one purpose is used for another (e. g. , female orgasm in primates, bird feathers, jaw bones exapted to inner ear bones in humans)
