A population of crabs live on a light-colored sandy beach. In this environment there is a population of birds that eat the crabs.

2. There are more light crabs, because they are better at obtaining food.
3. There are more dark crabs, because they are less likely to be seen and eaten by birds.
4. The eruption has caused all crabs to go extinct.
