What are Darwin's postulates of natural selection?
· There are more offspring produced than will actually survive to reach a reproductive age.
· There is genetic variation in all organisms.
· Some traits enhance the chance of survival in an environment. These traits are considered to be favorable.
· Organisms with favorable traits in an environment are more likely to survive and produce offspring. Thus, they are more likely to pass these favorable traits down to the next generation.
· When a particular trait is passed down in large numbers due to natural selection in an environment, it is selected for. It contributes to the success of an organism.
