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 4 postulates. 1) variation among individuals within a population 2) heritability of (some) trait differences (variation) 3) more offspring than can survive (variable reproductive success) 4) non-random survival and reproductive success. fitness. relative ability of an organism to survive and reproduce.
