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?

Here's a link to a lot of discussion on the topic.

The olfactory system is not just for smelling the morning coffee. It also is connected to the limbic system, influencing memory, pleasure, hormonal function, on and on.

Although a large number of the genes responsible for our sense of smell are called inactive or pseudo genes they may not be so inactive after all.

Can you imagine a man and woman tryign to date with hypersensitive smelling?

“Ewww- You stink!”

“No! YOU Stink”

“No! You Do!”

Our species would have died out a long time ago- That’s my theory and I’m sticking to it
