Simulate evolution with some colorful "critters" and carnivorous "beaky birds." Simulations are helpful to demonstrate processes like evolution that take place over many years. Observe how adaptations such as camouflage help organisms survive and pass on traits to offspring. Recognize evolution happening simultaneously in both the predator and prey (bird and critter) populations.
