Darwin's four postulates can be summarized as follows: Individuals in a population vary in the traits they possess. Some trait differences are heritable. Survival and reproductive success are variable among individuals in a population. Individuals with certain traits are more likely to survive and reproduce.[4] Darwin's Theory of Evolution - A Theory In Crisis Darwin's Theory of Evolution is a theory in crisis in light of the tremendous advances we've made in molecular biology, biochemistry and genetics over the past fifty years.
