For other species, these biological gender gaps can get even bigger.

Evolution under these conditions is called frequency-dependent selection.

Some phenotypes become “fitter” as they become more common ( frequency-dependent selection).

Evolution, it turns out, is a similar game, albeit one with much higher stakes.

The players in the evolution game aren’t just people in a bar; they’re all the individuals in a species.

One of the best parts about sex – besides the obvious, of course – is how much fun it can be. Connect the dots and connect with your partner at the same time.

Sure, intense and romantic sex is great too, but there is something really stimulating about being able to laugh while you’re getting down and dirty. The only expectation should be enjoying yourself and your partner.

Losers, as Mystery would say, have their genes “unapologetically weeded out of existence.” Winners can’t rest on their laurels for long, though.

In the same way that newcomers with snazzier outfits and snappier lines could challenge old-timers like Mystery, even established phenotypes are subject to new mutations.

Mystery’s winning game plan—behaving very differently from normal individuals—is an example of the latter.

A species’ ultimate goal—to survive and grow—hinges on the success of its phenotypes.

In the evolution game, you win by having a phenotype that helps you survive, mate, or reproduce your genes more than the competition.
