Principle 2: Overproduction and the struggle to survive
Principle 3: Different Survival and Reproduction (Survival of the Fittest)
Genetic Variation: Genetic Variation is when a certain species has a difference like two different colored grasshoppers.
Principle 4: Change in the Gene Pool
Overproduction and the struggle for existence: The struggle for existence is because the brown grasshoppers are seen better, making them more likely to be eaten. The green grasshoppers less likely to be eaten because they camouflage to the green grass.
