Final answer:
The four postulates of natural selection are 1) variation in traits within a population, 2) heritability of traits, 3) variability in survival and reproductive success, and 4) differential reproductive success based on trait advantages.
Step-by-step explanation:
The four postulates of natural selection, essential for the process to result in evolution, are 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.
The incorrect statements in the list include the ideas that all individuals in a population possess the same traits and that all individuals have equal reproductive success. These statements are not postulates of natural selection, as natural selection relies on variation within a population and differential reproductive success to drive evolution.
