- 2: Genetic Variation
- 2: Overproduction of Offspring
- Butterflies are very populated in the Regular forest. Their different color wings show natural variation in the population, and animals such as birds and wasps are constantly searching for food. The forest typically has the same type of weather all throughout the year.
- 4: Competition & Natural Selection
- In these butterflies there are two colors produced. One brown and the other blue. Thus, creating genetic variation among the butterfly population in the forest.
- 5: Adaptation
- Throughout the year the butterfly populations have rapidly increased. Thus, the butterflies in the forest is becoming more overwhelming as the days go by.
- Evolution Has Occured
- The blue butterflies are easier for the birds or wasps to see While the brown butteflies blend in with the tree bark making them hard to see. It's natural selection where the brown butterflies will continue survive and reproduce comfortably.
- Brown butterflies were obviously more likely to survive in this environment because of their ability to camoflouge in their environment. After various years of natural selection, this left most of the population of the new generation to brown butterflies. The offspring now carry the heritable trait of brown wings, making it easier to adapt and survive in their environment.
- Evolution can occur rapidly or slowly in an environment depending on the size of change and genetics in population. The genetic differences can include blue, brown, or multicolored wings, causing the butterflies to appear in different colors. In this environment specifically, the dominant genetic trait is brown wings.
