Final Answer:
1. At time 3, there are more gray mice and fewer white mice than at time 1. This happened because the hawk (bird) could easily see and catch the white mice on the gray sand, so more gray mice survived and had babies.
2. Most of the babies would have gray fur because the surviving mice (parents) are mostly gray, and they pass their color to their babies.
3. Gray fur increased fitness because it helped mice hide from the hawk and survive longer to have more babies.
