Document Summary
Three observations (by darwin: biological variation within all species, all species capable of reproducing at a faster rate than food supply, competition for limited resources. Creates variation in fitness some individuals are able to pass on favorable traits through offspring. Traits are inherited and passed on to the next generation. 3: over geological time, successful variations accumulate so that later generations may be distinct from their ancestors, geographical isolation may lead to a new species. Natural selection operatures on the features in an individual but populations evolve. Fitness: the relative reproductive success of individuals (will change as the environment changes) Wallace had same ideas as darwin through a separate trip, but upon realizing wallace was going to publish these ideas, darwin published a paper on his ideas. Neither were able to deduce the mechanisms by which evolution occurs gregor mendel did. Lecture 3: modern evolutionary theory & population genetics. Provided mechanisms of natural selection through breeding experiments with peas.
