Darwins 4 postulates. Variation exists among individual organisms that make up a population,such as variation in size and shape. Some of the trait differences are heritable,meaning that they are passed on to offspring. For example, parent flowers with long petals tend to have offspring with long petals.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.

Darwin 's accomplishment: establish truth of evolution, establish a mechanism for evolution (natural selection). Natural selection (which results in change in species) is an inevitable outcome of four attributes of nature ("Darwin 's postulates", according to the text):Darwin claimed that he proceeded “on true Baconian [inductive] principles and without any theory collected facts on a wholesale scale.”. He also wrote, “How odd it is that anyone should not see that all observation must be for or against some view if it is to be of any service!”.
