Darwin's Four Postulates
What can we find out?
The 4 Postulates:
(2) The heritable genetic variation of individuals in a species due to mutation and sexual reproduction.
(3) More offspring are produced in each new generation than can possibly survive.
(4) Natural Selection - Individuals that have certain traits are more likely to survive and reproduce.
1. Every individual organism within a population will vary when it comes to their traits
