If the universe was fine tuned for our life...

I don't think a chameleon qualifies as a sub reality....but lets set that aside for now. For a chameleon to do something like this:



Requires perception, retention of knowledge and information, planning, and problem solving. It requires a minimum amount of intelligence. Can you give an example of a chameleon which doesn't have a nervous system or brain?

Like I said. You're expanding and contracting your definitions to include only what you want to include. That's the Texas sharpshooter fallacy. A chameleon animal doesn't intentionally design the subreality which is what you were originally arguing for. First it was designed, then the product of intellect, then reduced to merely having a brain. You're rubber band man.
