Document Summary

Evolutionary psychology: evolutionary psychology is concerned with the evolutionary underpinnings of behavior understanding the adaptive significance and utility of behaviors exhibited by modern humans. Twin studies: studies find that identical twins show a greater correspondence in many traits than do non-identical siblings. Because mza twins share identical genetic material and no common environment, the correlations of mza twins directly reflect heritability: difference between mza and mzt twins directly estimates the effects of shared environment. The function of a feature: adaptionist view of the phenotype (the outward expression of an organism"s genotype; an organism"s physical characteristics and behavior. ) Polygyny: sexual behavior in which one male mates with more than one female, while each female mates with only one male. Then, the combined steroid hormone receptor complex enters the nucleus, binds to the dna and acts on genes. Steroid receptors are highly specific and psychologically interesting due to their high specific motivational effects.
