Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

According to the theory of natural selection, what is likely to happen to a population of birds after the seeds they normally eat are no longer available and all that is left are seeds that are harder to crack open? 
Note: a population is a group of individuals of the same species.

• The individual birds that already have the kind of beak that allows them to eat the seeds that are harder to crack open would be more likely to survive and reproduce.
• All of the individual birds would develop new beaks as they attempt to eat new seeds.  All of the birds would survive and reproduce.
• Some of the individual birds would try to develop new beaks so that they could eat the seeds.  Those birds would be more likely to survive and reproduce, and the other birds would likely die.
• Because the population of birds is all of the same species, they all have the same physical traits.  No individual bird would have an advantage in cracking open the seeds, and all of the birds would die.
