List all factors that lead to evolution in a species.

2. Section 5-4: artificial Selection
Essential Question:
How can a species be changed by its environment?
Learning Target
Explain the relationship between the factors of evolution and the adaptation of a species that results from competition for limited resources.

7. Artificial selection
Nature Selection = All Variations Artificial Selection = Humans pick most useful variations.

8. Artificial selection Fat pigs. Dairy Cows. Fast Horses.
For example, these are the animals that get to pass on their traits:
Fat pigs. Dairy Cows. Fast Horses.

10. Artificial VS. natural
Natural Selection: nature determines which organisms live on to reproduce.

11. Artificial VS. natural
Artificial Selection: humans decide which organisms should reproduce the most.
