  14. Evolution Continued

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

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

  17. 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.
