Postulate 1 – Individual members of a population differ from one another in many respects.
Postulate 2 â At least some of the differences among members of a population are due to characteristics that may be passed from parent to offspring. That is, they are heritable or genetic.
Postulate 3 – In each generation, some individuals in a population survive and reproduce successfully but others do not.
Postulate 4 â The fate of individuals is not determined by luck. Instead, an individualâs likelihood of survival and reproduction depends on its characteristics. Individuals with advantageous traits survive longest and leave the most offspring, a process known as Natural Selection.
