Main ideas to focus on:

1) Genetic mutations to the DNA code that cause changes in a trait are random events (they aren't predictable)

2) Once mutations have caused some variation in a trait, the process of natural selection on that trait can occur; Important: Natural selection is not random, but mutations are.

3) Generally, natural selection will predict that individuals with a version of the trait that help them survive and reproduce more than others will have more offspring in the next generation

4) Since the trait is genetic, offspring will inherit the favorable version of the trait from their parents, and each generation more and more individuals will have this version of the trait.
