Question

Directions: Select the correct graph. A moth population living in adeciduous forest relies on camouflage to protect itself from predators.These moths typically vary in color and are thus able to camouflage amongboth the light- and dark-colored trees of the forest. However, as sootemitted from nearby factories darkens the forest's trees, the mothpopulation begins to evolve. Which of the following distribution graphsbest represents the evolution of this moth population?A.B.C.orD.

Answer 1

In the graph, we can see how the original population ranged the same in each case, but considering the soot caused white moths to be more clearly spottable, and the black moths more imperceptible, the evolved population presented then a variation with respect to the original one. The graph that better represents this, is the first one, the A graph, since there we can see how a higher number of moths are restricted to the black moth part of the graph, than in the other graphs.
