The peppered moth simulation gave me a better understanding of natural selection and how it causes populations to change and evolve. The method used to conduct this experiment was to use two different sheets of white and pink paper, small white and pink dots, and place the different colored dots on different colored paper, and pick the dots up with forceps in under eight seconds. The method also consisted of collecting data and graphing it. This method had high validity because it was accurate and can be validated with events that happen in real life. The events that the simulation accurately represents are the events of Manchester, England. It represents how earlier on in time, moths were light colored because the trunks of the trees in the …show more content…
The graphs represent the data collected and visually show the answers to the problem statement: What is the effect of either white or pink backgrounds on the survival of white and pink organisms? Graph 1 shows the comparison of white and pink moths on a white background. What the results show is that pink moths are less likely to survive on a white background than white moths are. As the generations developed, white moths thrived and in the fifth and final generation represented the results showed that they had 106 white moths, while on the other hand the pink moths only had 36 moths living. The results depicting the comparison of white and pink moths on a white background show that there was a considerable downfall in pink moths, while there was a sizeable increase of white moths. Graph 2 shows the comparison of white and pink moths on a pink background. What the results show is that white moths are less likely to survive on a pink background than pink moths are. As the generations developed, pink moths prospered and in the final generation represented the results showed that they had 225 moths living, whereas the white moths only had 125 moths living. The results representing the comparison of white and pink moths on a pink background show that there was a decline of white moths, while there was an immense increase of pink
