Why PMS?

I was pondering the nature of life, and wondering exactly what purpose PMS would serve from an evolutionary standpoint. I mean, you can certainly see where ovulation fits it, with pheromones and all that, but what the heck good would being grumpy and nasty do you, except to drive away the male.

And therein lies the answer!!

If you’re PMSing, that means you didn’t get pregnant. Which means the male failed in the breeding because if you’re cycling normally, you should have gotten pregnant and when you didn’t then your body is blaming the male and attempting to drive him away so you can find a more suitable mate when ovulation arrives again a couple of weeks later.

Of course, this is relating back to when humans were not social, monogamous creatures living in communities. This would be before the times of true love and ’til debt..oops…death do we part’. Back in the days of live to eat, sleep, excrete, and reproduce. Back when evolution would have been influencing human development. Perhaps having the unsuccessful male leave because of nastiness served a purpose – opening the door for the next, more fertile, male! And, since you wouldn’t PMS once pregnant, then your fertile male sticks around, protecting the gravid female.

This is, of course, speculation, which is one of my favourite things to do. And, is of course not politically correct, which is one of my least favourite things. Let the comments role…looking forward to it!
