**Separated Species**

A population of mice live in a light, sandy environment. The majority of mice have light-colored fur, and the remaining mice have either medium-colored or dark-colored fur. A flood occurs in the area, creating a river that separates the population and changes the color of the ground on either side. After a long period of time, the water dries up and the two groups of mice are able to interact again. After the change, mice from different sides are unable to breed with each other. The pictures show the environment before, during, and after the change.

**Diagrams:**

1. **Original Environment:**
   - Shows a homogeneous light-colored sandy terrain.

2. **Environments after Separation by Water:**
   - **North Side:** Retains a lighter ground.
   - **South Side:** Displays a darker ground where the river initially was.

3. **Environment after Water Dries Up:**
   - The river is no longer visible, depicting a return to the conjoined environment, but with distinct ground colors.

**Table:**

The table presents the frequency of fur color across the populations when the mice were separated by the water.

|                  |  North Side                         | South Side                        |
|------------------|-------------------------------------|-----------------------------------|
| Generation 1     | Light 80% - Medium 15% - Dark 5%    | Light 90% - Medium 5% - Dark 5%   |
| Generation 5     | Light 65% - Medium 27% - Dark 8%    | Light 70% - Medium 10% - Dark 20% |
| Generation 10    | Light 51% - Medium 38% - Dark 11%   | Light 50% - Medium 10% - Dark 40% |
| Generation 20    | Light 20% - Medium 75% - Dark 5%    | Light 20% - Medium 6% - Dark 84%  |

**Question:**

Which claim can be made with the evidence in the passage?

- A. New species of mice are rare when the environment changes.
- B. The populations of mice on both sides did not change over time.
- C. New species of mice can emerge when the environment changes.
- D. The populations of mice on both sides eventually became the same color.
