explain the term "survival of the fittest"
this means that the healthiest and most fit organisms will survive much better than the rest of their species

explain how natural selection works
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.
500
explain how artificial selection works
Artificial selection is the intentional breeding of plants or animals. It means the same thing as selective breeding. Selective breeding is a technique used when breeding domesticated animals, such as dogs, pigeons or cattle. Some of these animals will have traits that a breeder will want to preserve.
