The four postulates of evolution by natural selection. V

Darwin recognized the process of evolution (natural selection). What are the four postulates of evolution by natural selection? (1) Individuals in a population vary. (2) The variation is heritable. (3) More offspring are produced than can survive. (4) Individuals differ in their production of offspring.Four postulates of natural selection, the outcome of which is evolution: 1. Individual organisms in a population vary in traits (size, shape, color, etc.).This condition is provided by Mendelian inheritance. 3. Variation in characteristics of the members of the population. 4. Variation in the fitness of organisms ...

In introductory textbooks, Lamarckism is often contrasted with Charles Darwin’s theory of evolution by natural selection.
