What Color Bead Bug - 1042 Words

Introduction The purpose of the lab was to see what color bead bug would survive the longest in the environment. By performing the experiment, natural selection was being tested. Natural selection is when organisms that are most suited to the environment survive and reproduce more successfully. Certain colored bead bugs would survive longer, because they blended in. The bead bugs that are a more prominent color stood out more and were eaten right away. This experiment displays how the population of bead bugs changes over the generations, due to the amount being eaten and the amount of bead bugs that were reproduced. Theory Evolution is â€Å"the process by which organisms have changed over time† (Biology 450). Charles Darwin is responsible†¦show more content†¦Some of the adaptations may include claws, behaviors, and the ability to camouflage (Biology 460). Darwin realized there was a connection with the way an organism survives and their environment. Different adaptations affect an organism s fitness and the type of environment (Biology 460). â€Å"The difference in rates of survival and reproduction is called survival of the fittest† (Biology 460). Organisms with characteristics that are suited for the environment have the ability to survive and reproduce. However, organisms that have characteristics that are not suited for the environment have a low survival rate and have a limited number of offspring (Biology 460). Natural selection relates to the lab because only certain colored bead bugs were able to survive. The bead bugs that had an adaptation of color were able to blend in. The bead bugs that had a color that stood out were often eaten first. The bead bugs that have a color adaptation on their side had a higher survival rate and were able to reproduce and have many offspring. The bead bugs that did not have a color adaptation stood out. They had a low survival rate and had little to no to offspring. If the clear bead bug is put in the environment then it will survive the longest, because it will be able to blend in with the colors in the habitat.
