1. Summary of Evolution by Natural Selection
1.Variation: Individuals vary from one another in many characteristics. The variation in inherited. 2.Overproduction: Species produce more young than will survive 3.There is a “selective pressure”: competition for resources (food, habitat etc.), or a change in the environment, or a predator…. 4.Survival of the fittest phenotype: The individuals with the most favorable characteristics will be most likely to survive and pass their genes 5.Favorable characteristics increase: Each new generation will contain more offspring from individuals with favorable characters than those with unfavorable ones, changing the population over time.

2. Summarize the five “steps” of evolution by natural selection by explaining and illustrating one of these examples:
