Question

the population of mice is in an environment with many black rocks.
mice with brown fur are less likely to survive and reproduce than mice with black fur.
after many generations, most of the mice in the population have black fur.
a sandstorm covers most of the populations environment with brown sand.
mice with brown fur are more likely to survive and reproduce than mice with black fur.
after many generations, most of the mice in the population have brown fur.

Explanation:

To determine the correct order, we analyze the process of natural selection:

1. Initial Environment: The population of mice is in an environment with many black rocks.
2. Survival Advantage (Black Fur): Mice with brown fur are less likely to survive and reproduce than mice with black fur (because black fur camouflages with black rocks).
3. Result of Selection (Black Fur Dominance): After many generations, most of the mice in the population have black fur.
4. Environmental Change: A sandstorm covers most of the population's environment with brown sand (changing the camouflage advantage).
5. New Survival Advantage (Brown Fur): Mice with brown fur are more likely to survive and reproduce than mice with black fur (brown fur now camouflages with brown sand).
6. Result of New Selection (Brown Fur Dominance): After many generations, most of the mice in the population have brown fur.

The correct chronological order is:

1. The population of mice is in an environment with many black rocks.
2. Mice with brown fur are less likely to survive and reproduce than mice with black fur.
3. After many generations, most of the mice in the population have black fur.
4. A sandstorm covers most of the population's environment with brown sand.
5. Mice with brown fur are more likely to survive and reproduce than mice with black fur.
6. After many generations, most of the mice in the population have brown fur.

(If this was a multiple - choice question with options, the answer would be the option that matches this order.)
