Transcript of 5.02 Evolutionary Relationships

How do the original and surviving prey populations compare?



How did the colors of each type of prey affect its population size over time?



What color(s) seemed to camouflage the best in this habitat? What color(s) seemed to stand out the most?



How do you predict the data would change if you continued? Explain your answer.

How would these results change if the colors or patterns of the habitat were to change?




Identify at least two things that are unrealistic and two things that are realistic about this exercise.





What traits could help a predator be more “fit” in this model environment?


Describe other adaptations besides color that could affect an individual’s survival.

At the end, the 4/5 surviving prey did not reach over 25. However, the one population that survived through a lot was Orange.
Some colors were a lot stronger than others. Orange was the strongest population, while Red was the weakest.
Orange
I think that Red would eventually go extinct, Orange would keep increasing, Purple might start to regain it's population, Blue would eventually go extinct, and Yellow would remain neutral.
If the patterns of the habitat or colors were to change, then I think the population of the colors would either increase or decrease depending on if they were able to adapt well enough to the new habitat.
Two unrealistic things are that (1) there would be a lot more predators than just two, and (2) the generations would start at an even number such as twenty. Two realistic things are (1) the predators would choose the prey at random, and (2) the population would vary such as they did in the exercise.
Probably being able to run extremely fast and being able to blend in with the surroundings.
Appetite, like if a food source were to run out and they would have to change their appetites easily and being able to adapt to a different environment if it were to change.
