Question
A new predator is introduced into an ecosystem. Over several generations, there is an increase in the speed of a prey species.
Which evidence would help support that this change is due to natural selection and not just a correlation?
(1 point)
Responses
Genetic analysis showing changes in genes of the prey.

To support that the change in the speed of the prey species is due to natural selection and not just a correlation, the strongest evidence would be:
**Genetic analysis showing changes in genes of the prey.**
This evidence would provide insight into the adaptive changes occurring in the prey population at a genetic level, indicating that the faster individuals are more likely to survive and reproduce in the presence of the new predator, thus demonstrating natural selection in action.
