Section 2: Discussion
In the graph of percentages of frequencies, the percent of frequency that gradually
increased was the blue “organisms”, the orange “organisms” percent of frequency
gradually decreased then at generation 4 began to return to its original state. By
generation 6 the blue “organisms” frequency had become the same that it was in
generation 1. The yellow “organisms” percentage of frequency gradually decreased to
generation 2, stayed the same for 2 generations, and then gradually decreased until
generation 6. The table showed relatively similar numbers for all the “organisms” up
until generation 5. At which there is a huge difference between the number of blue
“organisms” and yellow “organisms” At generation 6, there is a huge difference in
the population between all three coloured “organisms”.
After doing this experiment the data in our results proved that our hypothesis was
correct. Our group had predicted that the yellow chips would have the lowest number
found, and what was true after the experiment had been finished. This experiment has
proved to us that when a species adapts well to their surroundings, the survival
rate of the species drastically increases. Our group also noticed that the
“organisms” that were the brightest colours declined the fastest in population. The
colours blue and orange had the best camouflage towards the environment, and
yellow’s camouflage did not have good camouflage, therefore its population quickly
declined. The natural selection that occurs within the results of this experiment is
disruptive. An example of this is humans and their wisdom teeth. Over time the human
jaw has become smaller which has made the human mouth to hold to small wisdom teeth.
Most people need surgery to remove their wisdom teeth, but over time some people
have been born without them. Since wisdom teeth are no longer necessary, evolution
makes the decision to remove the trait and save on the unnecessary energy and effort
being used. The improvements that could have been made towards this experiment
include making it more realistic and comparable in real life situations. Using a
computer software that automatically start and stops timing in order for the results
to become more accurate. Finally, using a variety of dark and bright colours to
provide a more in-depth comparison.
