Quick Write:
1. There are three necessary conditions that must be met for natural selection to occur. The first is there must be variation in characteristics. Different individuals in a poplulation must have different traits.
2. The next condition is there must be a difference in fitness. The different traits must help the individual survive and reproduce.
3. The condition is that the trait that affects fitness must be inheritable. The trait must be able to be passed by genes from one generation to the next.

- What is the different trait the surviving cactus has?
2. The next condition is there must be a difference in fitness. The different traits must help the individual survive and reproduce.
- How did the different trait help the one cactus survive and reproduce?
3. The condition is that the trait that affects fitness must be inheritable. The trait must be able to be passed by genes from one generation to the next.
- How do you know that the different trait was passed to the next generation?
