Document Summary
3 premises of natural selection: over-reproduction within a species, variation exists within a species, and some variants are more fit than other. Phenotypes is the outward expression of your genotype. Individuals who are more fit reproduce more, and if the variation is genetic, it will be transmitted to the offspring. 2 keys to natural selection: reproductive success. Passing genetic material and survival of offspring: differential fertility. Some individuals are reproducing more than others (differential gene reproduction) Sexual selection - used to explain darwin"s questionable findings such as colorful animal markings that attract mates. Inclusive fitness - (hamilton, 1963) need to compute an organism"s direct reproductive fitness and an organisms indirect reproductive fitness. Indirect reproductive fitness includes copies of one"s traits in other related individuals. How people currently are not should be. Psychological processes that resulted in high fitness in the ancestral environment may be maladaptive or morally condemned in the present.
