This line graph shows how some phenotypes were more successful than others. This is an accurate representation of natural selection. The dark blue, pink, and orange phenotypes became extinct before the experiment was even finished. The successful phenotypes were green, purple, and yellow.

Conclusion This experiment was done to test and observe how natural selection works. The Construction Bugs were tested in a flowery meadow to see which colored bugs survive and which do not. Natural Selection occurred because the bugs with odd colors that stood out in the flower meadow did not survive. These were the orange, dark blue, and pink bugs.

The hypothesis of the experiment predicted that 50% of the remaining Construction Bugs will be green, 25% of the bugs will be yellow, and the other 25% will be purple. The results of this experiment supported this experiment. The percentages of the remaining bugs was exactly what the hypothesis stated. In the line graph, the orange, dark blue, and pink bugs died out quickly. This shows how these bugs are not fit enough in this environment.

The final results of 10 yellow bugs, 10 purple bugs, and 20 green bugs support the hypothesis. The

Other flaws include forgetting to flip a coin for the mutations, which can result in having less orange, purple, and green bugs. This experiment could be improved if the experiment was a life scenario that was similar to this experiment. This experiment does not represent natural selection fully because the investigator is hand-picking the bugs that will not survive. This experiment is very limited because in the real world, there is nothing to control how many bugs a predator can hunt. In this experiment, only 20 bugs were allowed to be hunted, which is not realistic. The next step in this experiment could be to do this experiment in real life and observe the process of natural selection with real
