Document Summary
Cole"s paradox: what is the big advantage of being perennial vs. being annual, annual = semelparity = reproducing once before death = big bang , perrenial = iteroparity = multiple reproductive cycles over lifetime. Senescence & hamilton"s forces of selection: any delitirious mutation before reproduction will take us out of the population, afterwards, it will be given to the children, therefore, a selection pressure against you, because are in the population. When did the different groups meet back up again: know generally the different types (neanderthals, homo erectus, what were they doing, what seperates humans from other apes? (there is a summary slide on this in the notes) Selflessness: know different theories, group selection -> we act for the betterment of the species (proven wrong, multilevel selection, know prezygotic and postzygotic barriers, pre mating behaviour is not responded to, post sterility, unable to fertilize.
