Compare and contrast natural selection and selective breeding.
Natural selection is when organisms with traits best suited to their environments are most likely to survive and reproduce.
Selective breeding is the deliberate breeding of plants or animals for desired traits. In natural selection, the environment is affecting the traits that are passed on to the offspring. In selective breeding, the breeder selects the traits.
Artificial selection is also known as survival of the fittest.
