Just give the proof, stop playing games. Every time I ask you to give proof of a statement you start with these silly evasions. Cough it up. Cough up the proof that dinosaurs did not have mammary glands.
So you give up, right? Note that I did not say "proof." I said "provides a framework in which dinosaur mammaries are predicted out."
If you give up, say so. But think about it. This would be a good one to show that you can answer.
