If the theory is testable and correct, then a biologist should be able to observe evolution by natural selection in a real-life population.

If the theory is testable and incorrect, then biologists shouldn't be able to observe natural selection.

If the theory is testable, then biologists should be able to test each postulate of the theory separately.

If the theory is testable, then all of the listed responses are correct.
