BIOL 1510 Lecture Notes - Lecture 1: Divergent Evolution, Ichthyosaur, Medium Ground Finch
Document Summary
White mice used to be brown and depending on their environment in florida changed to more white mice. Some reasons people may not understand evolution can be from religion and not understanding and agreeing with many theories. Ex: the genetic theory of natural selection by r. a. fisher: not all theories have to be accepted. Or just declare the theory off-limits (not good) Ex: in the past it was said women"s ovaries shrink if they went to college. Darwin"s theory of natural selection: variation- different traits over generation, consequences- the ones with certain traits can survive better than others, heritability- offspring resemble parents in these qualities. Industrial revolution: changes the composition how tree look and how our animals live. Ex: the moths changed from light to dark. They rely on light for energy, so less caused them to change. They changed black now because of natural selection.
