Fish that live deeper in the ocean have eyes that are larger than fish that live in shallow waters. This suggests an adaptation to low light environments.

What evidence would support a causal explanation for this adaptation?

The best evidence that would support a causal explanation for the adaptation of larger eyes in deep-sea fish due to low light environments is:

Experimental evidence showing that larger eyes enhance the ability to see in low light.

This response provides direct evidence of causation, demonstrating that the size of the eyes influences visual capabilities in low-light conditions, supporting the adaptation hypothesis.
