4 postulates of natural selection

Identify the four postulates of natural sel

Darwin's Postulates (Ideas) Individuals in a population have variations that make them unique. Some of these variations are passed on to offspring.Natural selection is an inevitable outcome of three principles: most characteristics are inherited, more offspring are produced than are able to survive, and offspring with more favorable characteristics will survive and have more offspring than those individuals with less favorable traits.
