- (Aron P: 3) 1:Population
- 2: Genetic Variation
- 2: Overproduction of Offspring
- Squirrels are very populated in brookville lake. Their different color furs show natural variation in the population. Their home also features predators such as hawks or foxes. The forest can get extremely snowy in the winter and rainy in the spring season.
- 4: Competition & Natural Selection
- Genetic variation gives all the squirrels notably different characteristics. The main one is their fur color, some are very dark, some are light brown. Genetic variation is the genes creating different individuals in the same population.
- 5: Adaptation
- Kicking off the winter season, many new baby squirrels are born in various amounts of colors. However it's alarming how many new Squirrels are born aka, overpopulation. Shelter, safety and especially food will become scarce.
- Evolution Has Occured
- The darker fur squirrels are easier for its predator, the fox, to hunt. The squirrel with the lighter fur can hide easier and the brown squirrels can almost camouflage in the dirt. It's natural selection where the best suited for the environment will survive and reproduce comfortably.
- Brown fur squirrels were 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 brown squirrels. The offspring now carry the heritable trait of brown fur ,making it easier to adapt and survive in their environment.
- Evolution can happen quickly or slowly in an environment depending on the size of change and genetics in population. The genetic differences can include a short/long tail, light/dark fur, short/long back legs, big/small ears etc. In this environment specifically, the dominant genetic trait is brown fur. The environment of the forest gives a sort of layout to whom can adapt , survive and create offspring.
