Four postulates of natural selection
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.Darwinian Theory of Evolution explains that evolution is the result of natural selection, and natural selection is biased by the inherited characteristics of organisms. The adaptive ability of organisms is the one which helps organisms in evolution through natural selection. According to Jean-Baptiste Lamarck – a French naturalist, he ...
