- (Name P: 3) 1:Population
- 2: Genetic Variation
- 2: Overproduction of Offspring
- Rabbits are very populated in the Los Alamos forest. Their different color furs show natural variation in the population. Their home also features predators such as eagles or white 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 bunnies notably different characteristics. The main one is their fur color, some are very dark, some are light brown and others are snowy white. Genetic variation is the genes creating different individuals in the same population.
- 5: Adaptation
- Kicking off the winter season, many new baby bunnies are born in various amounts of colors. However it's alarming how many new rabbits are born aka, overpopulation. Shelter, safety and especially food will become scarce.
- Evolution Has Occured
- The darker fur bunnies are easier for its predator, the grey wolves, to hunt. The bunnies with the lighter fur can hide easier and the white bunnies can almost camouflage in the snow. It's natural selection where the best suited for the snowy environment will survive and reproduce comfortably.
- White fur bunnies 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 white bunnies. The offspring now carry the heritable trait of white 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 white fur. The environment of the snowy forest gives a sort of layout to whom can adapt , survive and create offspring.
