Your team arrived in the Galapagos Islands at the end of a long drought on the island Daphne Major.  Before the drought, some of the medium ground finches had large, deep beaks, while others had thinner, shorter beaks.  The larger and deeper the beak, the easier it is for the beak to crack hard seeds.  Likewise, smaller, thinner beaks are best for gathering and eating soft, small seeds.  The image shows photos and the data table of measurements from before and after the drought. 

The number of medium ground finches with small beaks on Daphne Major ______.

• Increased

• Decreased

As a result of the drought, the diet of medium ground finches on Daphne Major consist mainly of:

• Soft Seeds

• Hard Seeds

England began burning coal in the mid 1800s. Dark soot and black smoke are products of coal, which over time coated the nearby trees. The graph shows population changes in the peppered moths species in England.

Select two statements that may explain the changes in the population of peppered moths during this time.

• The environment favored darker coloring in peppered moths

• Darker peppered moths ate the lighter peppered moths

• Dark coloring was a trait that helped peppered moths avoid predators

• Peppered moths turned a darker color as they aged

Peppered moths have two different variations of wing color--light and dark. Prior to the industrial revolution, most moths were light colored. Then, in the mid 1800s, England began burning coal. Dark soot and black smoke are products of coal, which over time coated the nearby trees and the number of dark colored moths increased.

Which statement explains why dark colored moths were found after the trees became darker?

• The dark moths mated with other species of dark moths

• More of the light colored moths switched to asexual reproduction

• More of the dark moths survived long enough to reproduce

• Light moths were better able to avoid predators
