Question

39 multiple choice 2 points what was dr. kettlewells main conclusion from his 1950s experiments with the peppered moths? natural selection favored moths whose coloration matched the environment the moths color change was caused by pollution directly altering their genes both light and dark moths were equally camouflaged regardless of conditions moths changed color to match their surroundings by choice

Explanation:

Dr. Kettlewell's experiments showed that in polluted areas (with dark - colored tree trunks), dark - colored moths were less likely to be preyed upon (because they were camouflaged), and in unpolluted areas (with light - colored tree trunks), light - colored moths were less likely to be preyed upon. This is an example of natural selection. Pollutants do not directly alter the genes of moths to change their color. Also, light and dark moths were not equally camouflaged in all conditions. Moths do not change color by choice; it is a result of genetic variation and natural selection.

Answer:

Natural selection favored moths whose coloration matched the environment.
