Darwin's 4 principles.
The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.

The four proposes suggest the fundamental viewpoint of the Origin of Species. These thoughts are the essential ideas of the hypothesis of regular determination, and they make up the focal principles of development. The individual organism that make up a population vary in the traits they posses, such as their size and shapes.
