You do understand the principle?

How about this principle:

Humans share with mammals about a thousand genes for the sense of smell. But in humans, a third are inactive.

So humans have the gene responsible for the joy dogs experience while butt snuffing, and humans can give it a pass.

But hey, if the need arises, the Designer has foreseen it.

So how does evolution explain it?

If humans don't need it, why are the genes there?

If they evoloved for a reason, why aren't they being used?

Restating, crudely, that you don’t know what the function of something is so it has no function makes the point. Thank you.
