Evolution

3. Type of selection pattern when ONE extreme is favored
5. Type of selection pattern when the intermediate traits are selected for
10. Members within a species exhibit differences that can be inherited
12. Type of selection where humans determine which traits are most favorable
13. When small populations change over short periods of time due to pure chance
14. Mistakes in DNA that can result in new traits

1. The factor/reason some organisms' life is threatened
2. When a natural disaster/disease randomly wipes out portion of population
4. Occurs when food, mates and other resources are limited
6. Any trait that is heritable and increases fitness
7. When there are more offspring than can survive
8. Having a greater chance of surviving and reproducing
9. When extremes are selected for and the intermediate traits are selected against
11. Type of selection where the environment (nature) determines which traits are most fit
