Principle 2: Overproduction and the Struggle to Survive
Principle 3: Differential Survival and Reproduction (Survival of the fittest)
There is different genes within the population of the rattlesnakes. Some Code for blue skin, while others code for brown/grey skin.
Principle 4: Change in the Gene Pool
There is more offspring being born than the amount of blue rattlesnakes that can survive. The blue snakes are struggling to survive, as the hawks are eating them as they are easier to spot.
Organism: Rattle Snake Environment: Desert Trait Selected for: Brown/Grey color of skin Adaptation Type: Physical (Camouflage)
Only the fittest rattlesnakes will survive. In this case it would be the brown/grey rattle snakes, as it can camouflage. However, the blue rattle snake is not able to camouflage so it get eaten and can not serve and reproduce.

The population of rattle snakes in the desert is changing to more brown/grey skin. The brown/grey rattles snakes are able to survive and reproduce passing on their genes, which leads to more brown/grey rattlesnake than blue snakes in the desert.
