According to the theory of natural selection, what would happen to a species of lizards when a new predator is introduced into the environment where the lizards live? A. The lizards that already have the physical traits needed to avoid the new predator would be more likely to survive and reproduce, and the ones that do not would be less likely to survive and reproduce.

B. All of the lizards would try to develop new physical traits to avoid the new predator.

C. Some of the lizards would try to develop new physical traits to avoid the new predator, and the other lizards would die.

D. Because all lizards of the same species have the same physical traits, one lizard would not have an advantage over another lizard. They would either all survive or all die.
