Evolutionary Relationships
Hypothesis: Prey that is camouflaged in its habitat are harder to spot, and get to live long enough to pass on their genes which means the colors of the population that don’t fit in with the environment will eventually die out. Therefore, white will survive, and red will die out.

How do the original and surviving prey populations compare? Some of the populations rose, while others decreased.
How did the colors of each type of prey affect its population size over time? The colors that were less noticeable and eye-grabbing had a substantially higher population than the ones that were attention-grabbing.
What color(s) seemed to camouflage the best in this habitat? What color(s) seemed to stand out the most? White, and yellow seemed to camouflage the best, and red and blue seemed to stand out.
How do you predict the data would change if you continued? Explain your answer. I think eventually the attention-grabbing ones would die out since each generation they decrease more and more.
How would these results change if the colors or patterns of the habitat were to change? It would affect the colors that are being camouflaged, and the ones that are eye-grabbing, overall affecting the survival rate of all of the colors.
Identify at least two things that are unrealistic and two things that are realistic about this exercise. Two unrealistic things is, that it’s got a bit of random chance involved, and that since the humans are the prey, they aren’t colorblind. However, the camouflage is realistic, and the eye-grabbing colors are also realistic.
