Mice Evolution
Текст на Статията
- Jayden Lynn P.2 1:Population
- 2: Genetic Variation
- 3: Overproduction of Offspring
- There is a high population of mice in the woods. Their color gives a example of natural variation in the mice population. In their habitat there are predators such as foxes and hawks. Different parts of the woods, there's different colors of soil.
- 4: Competition & Natural Selection
- The difference in the characteristics of mice, is from Genetic Variation. The genes that cause things in the same population is Genetic Variation. One of the main differences is the color of the fur/hair.
- Evolution Has Occured
- During this time of year, many mice are born. The number of mice born caused overpopulation and causes the amount of space and food to become limited.
- 5: Adaptation
- The fur color of the mice determines its difficulty for its predators to hunt. The mice with the lighter fur can hide easier in areas such as rock or stone and the darker ones can almost camouflauge in soils, grass, etc It's natural selection of environments where they can nearly camouflage will survive and reproduce comfortably.
- Evolution does nor occur always in the same amount of time of way. Color and size are both different examples of genetic variation. Specifically in this environment the mice are small but vary in color depending on their suroundings. The environment of the woods gives the mice place where they can wither adapt to surive or to die off.
- Darker fur mice were more likely to survive and reproduce. After years of natural selection, most of the new generations are going to be darker colored mice. The new babies carry the darker fur and are able to adapt and survive more easily in their environment.
