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)
Data showing that increased speed coincided with the predator’s introduction.
Climate data showing no significant temperature changes in the ecosystem.
Observations that faster prey have a higher survival rate.
Genetic analysis showing changes in genes of the prey

The evidence that would best support that the change in the prey species' speed is due to natural selection, rather than just a correlation with the introduction of the predator, is:
**Observations that faster prey have a higher survival rate.**
This evidence demonstrates a causal relationship between increased speed and survival, which is a key component of natural selection. It shows that the faster individuals are more likely to survive and reproduce, leading to the increased speed in the population over generations.
**Observations that faster prey have a higher survival rate.**
This evidence demonstrates a causal relationship between increased speed and survival, which is a key component of natural selection. It shows that the faster individuals are more likely to survive and reproduce, leading to the increased speed in the population over generations.
