- (Name P: 3) 1:Population
- 2: Genetic Variation
- 2: Overproduction of Offspring
- Snakes live in the desert where there are not very many places that these animals can hide if they aren't the right color. Unfortunately for those snakes that are different colors, which shows genetic variation, they are very unlucky.
- 4: Competition & Natural Selection
- Genetic variation gives all the snakes notably different characteristics. The main one is their color. Some of them are darker colors and others are bright. Genetic variation is the genes creating different individuals in the same population.
- 5: Adaptation
- All year long, baby snakes are born in various amounts of colors. However it's alarming how many new snakes are born. Shelter, safety and especially food will become scarce.
- Evolution Has Occured
- The brighter colored snakes are easier for its predator, the to hunt. The snakes that are darker can hide easier, but the brighter cannot. It's natural selection where the best suited for the desert environment will survive and reproduce comfortably.
- Darker snakes are more likely to survive and create more offspring than any other. After various years of natural selection, this left most of the population of the new generation to be dark. The offspring now carry the heritable trait of dark ,making it easier to survive in their environment.
- Evolution can happen quickly or slowly in an environment depending on the size of change and genetics in population. In this environment specifically, the dominant genetic trait is dark/green skin.
