The type of evidence needed to establish a causal relationship between fur thickness and survival rates is:
Experimental evidence that shows rabbits with thicker fur can survive better in cold environments.
This type of evidence provides a direct demonstration of the effect of fur thickness on survival, indicating a causal relationship rather than just a correlation.
