4. Describe Darwin’s four postulates for natural selection by filling in the summary table below. Postulate Description Overproduction Individuals of the same species have natural variations in their genetic traits. Some of these variations give an individual an advantage – increasing their chance of surviving and reproducing. CompetitionDuring his voyage, and in the years after, Darwin developed and refined a set of ideas that could explain the patterns he had observed during his voyage. In his book, On the Origin of Species, Darwin outlined his two key ideas: evolution and natural selection.

It denotes Darwin’s specific view that evolution is driven mainly by natural selection. Learn more about the principles of Darwinism in this article.Darwin's four postulates (Variance, heritance, more than survive, surv/rep not random) 1. Individual species are variable 2. Some variation is passed on to offspring 3.
Darwin had the following ideas regarding the theory of natural selection: Species keep on evolving or changing with time. As the environment changes, the requirements of an organism also change and they adapt to the new environment. This phenomenon of changing over a period of time as per the natural requirements is called adaptation.
Today, biologists boil Darwin's four postulates down to two conditions that result in evolution. What are these conditions?
