The prey would increase in numbers, since their predator is now extinct.
The biggest evidence of natural selection is the progression in the morphology of fossil over time. Some of the fossils are of extinct species. This evidence point to the fact that species evolved from other species, gradually evolving new physical features. This is related to the environment in which they lived in since their morphologies allowed them to be well adapted for their environments.
