How Does Competition Change A Species Change Over Time

Species do change over time because of competition, adaptation, the environment and the history of the species and the earth. Competition makes a species stronger, faster and more agile. In order to survive, a species has to adapt to its environment and other organisms in that environment. Competition is only one of the reasons species change over time. In activity 3, the finches have different types of beaks. If a finch with a small beak goes up against a bird with a larger beak in the fight over bigger seeds, the finch with the larger beak would win. The finch with the smaller beak wouldn’t survive as long. When an organism dies there are unable to pass on their genes to the next generation. During the fruit loop lab our class had to compete for the cereal pieces. The more competitive and faster students got the most fruit loops and where able to survive. This shows that competition does change a species over time because …show more content…
During the mouse lab, when the ground was darker there was fewer light colored mice because they were unable to survive. These light colored mice would stand out and be eaten. If a finch is in an environment with only seed to eat, when their beak is meant for insects, they would have to adapt. If they couldn’t adapt they wouldn’t survive. Finally, in the bunny lab, the trait for brown fur was recessive, so there was more white bunnies than brown. When the wolves were introduced, all the white bunnies died because they couldn’t be camouflaged. In conclusion, adaptation shows change in a species because there physical traits have to change in order to
