To establish a causal relationship between fur thickness and survival rates, the most appropriate type of evidence would be:
**Experimental evidence that shows rabbits with thicker fur can survive better in cold environments.**
This type of evidence can provide a direct link between fur thickness and survival rates by demonstrating how changes in fur thickness affect the rabbits' ability to withstand cold temperatures.
**Experimental evidence that shows rabbits with thicker fur can survive better in cold environments.**
