That is an example of adaptation. Adaptation has been commonly noted long before Darwin. No one denies adaptation. The question is not IF animals adapt the question is HOW? and HOW MUCH?

This article doesn't address either of these things.

This question just shows that you don't even know what the debate is about.

So Ill tell you.

One debate is does macro evolution happen.

The other debate is are random mutations the cause of evolution?

So address the actual issues when you post these kind of questions.
