The outcome of each genetic bird recipe is a capuchino finch that looks differentone species with a black throat and gray cap, another with a white throat and gray cap. A geographically continuous population has a gene pool that is relatively homogeneous. Its rather like two cooks using the exact same ingredients for spaghetti sauce, but using a different recipe, varying when and how much of each ingredient is added, so the two sauces taste quite different. Yes, all individuals can change a little and pass those changes on to their offspring Yes, some individuals can change a little and pass those changes on to their offspring Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring No, species do not change even after many generations, so individuals of the same species would not look different Submit.
