I agree with that...

That doesn't mean that there aren't more out there.

It doesn't mean that the shaking of the head when excited or scared is NOT an advantage in the wild.

It doesn't mean that the corkscrewing can't be used to attract prey.

It doesn't really mean anything in regards to the topic at hand.
