Melanie Larson BIOL 101 GL Kiran Sapkota March 16, 2010 Natural Selection - Group1 Results (Tables 1 and 2 attached.) (Graph of table 2 attached.) When conducting this experiment it was apparent that the black moths had a much higher survival rate when compared to the white moths. In contrast between group 2, it was also observed that the black moths continued to have a much higher survival rate than the white moths. Discussion According to the lab manual (p.79) Natural selection is a non-random process that favors adaptive traits .

This is because the visual traits of the black moths blended with the environment better than the white moths, making it easier to choose the white moths first.
