The trait must have a function. Traits must do something for natural selection to take place. Advantage. To be selected for passing on to descendants, the trait must confer an advantage on the organism that has it, or make the organism more fit for survival in its environment. Origin.Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. For example, some beetles are green and some are 3.1 The Variation Principle. Natural selection will only lead to evolution if there is genetic variation in a population. Such genetic variation may be manifested as morphological, physiological, or behavioral (phenotypic) differences among the population’s members, but we know that the ultimate sources of variation are random mutations, …Explain the 4 main principles of natural selection.
