Document Summary
Non-directional: there is no specific end goal, no one species is more evolved than the other. Survival of the fittest: it means how many times you pass on your genes, natural selection the strongest do survive. This doesn"t matter unless you pass on your genes. You are fit as long as you produce offspring: survival of what"s good enough. If you"re good enough to reproduce you"re good enough for natural selection: stephen hawking v aaron rodgers. Since stephen hawking has kids, even though he has a disease and aaron. Rodgers is more fit hawking is actually more fit since he has had more offspring. Homologous traits are traits from a common ancestor: chimps and humans both don"t have tails, horses and humans have similar bone structure, animals with lateral symmetry. Dolphins have flippers and fish have fins. Drift = random changes in frequency of diff mutations.
