The four principle or postulates of Darwin are - variation , inheritance , selection and time. these all are considered the evolutionary component natural selection mechanism.
One is origin species by means of naturally selective mechanism, then preserve in the struggle of race of life.Darwin selection is mainly depends on the environment and heritable variations.All species of organisms which arise through natural selection of survive and reproduce.
