Some anatomical structures are developed by organisms as adaptations in the way that they move or in response to the particular conditions where they live. We sometimes see similar adaptions in several different organisms. Some anatomical structures seen in different organisms indicate a close evolutionary link between those organisms. Considering the structures shown, which pair of organisms likely has the closest evolutionary history?

• bats & humans

• bats & birds

• insects & birds

• insects & humans

• humans & birds

A deer is a four-legged mammal found in many different places of the world. Deers are herbivores, and have a diet consisting only of plants. If you were to place deer on this cladogram, which location would be the most accurate based on their known traits?

A group of biologists studied the beaks of seed-eating birds called finches. Over several years, the scientists found that a drought caused the birds' favorite seeds to become harder. The scientists also measured the size of the beaks over the same period. They created a graph of their findings. What can the biologists conclude from the data?

• The birds grew harder beaks so that they didn’t starve.

• Birds with larger beaks were better able to eat the harder seeds.

• Birds with smaller beaks found mates with bigger beaks to help them feed.

• Smaller birds found another source of food because they could not open the seeds.

The world map here shows two factors: 1) the growth rate of populations in certain parts of the world and 2) the number of endangered plant species. Countries in white have low population growth rates and are not included in the map’s data. Which observation could you use to support the argument that as human populations increase, negative impacts on Earth increase?

• About half of the map is medium or dark gray.

• Darker areas on the map have the largest circles.

• There are light areas of the map on all continents.

• Medium-gray areas on the map have the most circles.
