Darwin's 4 postulates
The individual organism that make up a population vary in the traits they posses, such as their size and shapes. Genetic that lead to structural, passed on to offspring, for example; Tall parents tend to have tall offspring. many more offspring are produced than can possibly survive. Only some individuals in the population survive long enough ...Assuming that humans evolved from apes is not really an assumption in Darwin’s theory. It’s rather a consequence of the assumption of the tree of life. However, because it is controversial, it took a major place in debates around the theory of evolution. That’s why so many people have tried to confirm or refute it.Postulates are mathematical propositions that are assumed to be true without definite proof. In most cases, axioms and postulates are taken to be the same thing, although there are some subtle differences.

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. Origin. Darwin's five postulates of natural selection are: 1. More organisms are born than can survive. 2. There is variation -- some are better at survival and reproducing. 3. This variation is heritable. 4.2) Some of the trait diffs are heritable (pass traits down) 3) survival and reproductive success is highly variable. 4) subset of individuals that survive best and produce most offspring is not a random sample.

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.The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees.
