I just wonder if there's any self-interest here that we're watching.

It's because it's written down here on the script.

LAUGHTER

You wrote that.

I remember you doing that, crossing out the other one.

Is there a monkey that wears a card?

And you went, oh, I don't want to do that.

So it's the males that are colourful?

And is it the females that are primarily making the choices?

The through line we see is that the male remains the idiot.

And remembers to lift the tail up so it's not dangling down to give away where it is.

And you mentioned genetics.

So in terms of the traits that will be attractive beyond the colour, what are the traits that the females are looking for?

Has that changed in terms of the understanding of humans, though?

Because I remember when we had Matthew Cobb on a while ago, and he was saying that actually the olfactory senses in humans during kind of dating, mating, is not quite what we thought it was before.

But we're the ones who shower and put scent on and do stuff.

So we're messing with a system to try and game it.

When actually, if we left alone, we'd probably mate more successfully with people who were better fit for our immune system.

OK.

Well, thank you for giving me a retrospective excuse.
