15. 3 things that effect Natural Selection • 1. Overproduction • 2. Competition • 3. Variation

16. Evolution Continued

17. Overproduction • Too many offspring are produced for the amount of resources available

18. Competition • Organisms compete for food, shelter, etc.

19. Variation • Variation is adaptation. • Organisms have the ability to 1. blend in (camouflage) 2. obtain food (sharp teeth, sense of smell, etc.) 3. Protection (quills, odors, etc.) 4. Helps it to move (speed, climbing, etc.) When adaptation occurs, is happens through generations.
