In a city in Australia there is a population of moths that live in the grass, rarely taking flight except for short journeys. There are two phenotypes for wing color: green and beige. The largest predator of moths are birds and bats that prey upon the moths as they rest upon blades of grass. Green moths fare better in wet conditions when the grass takes on a lush green color and beige moths fare better in dry conditions when the grass turns a dry brown color. Percentage of Moths of Each Color (a) Identify which color moth was the most plentiful between 1969 and 1995 ? (b) Explain why the lines of the graph never exceed 100 ? (c) Predict during which years there was a drought? (d) Explain how natural selection led to the rise of the beige moth in the late 1970 s?.
