If Darwin’s four postulates are true for a given population, is there any way that evolution can not happen? What does this imply about whether evolution is or is not occuring in most populations today?What are Darwin's 4 postulates? 1.) Individuals within a population differ from one another (variation within a population). 2.) The differences are, or at least in part, passed from parents to offspring (variation is HERITABLE). 3.)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.

The four main ideas of Darwin's evolutionary theory are variability in populations, overproduction of offspring, competition for resources and inheritance of traits. Variation provides advantages to some members of a population. The surviving individuals pass their traits to the next generation.
