Human Evolutionary Selection

So I was at work listening to my podcasts, sciencey and skeptical ones, and I stopped when I heard one that sounded like rape.  The male insect has this odd antennae that it uses to grapple females and when grappled it locks e female in place so he can mate her.  All the time the female is struggling to get away.  You see female insects that mate often are at increased risk of death through predation; twice the risk.   When scientist removed the genes that made the rape antennae, the number of successful matings dropped from one in eight to zero.  This insect had evolved to be raped.

I had taken it as a given that I, all humans, had a rapist father somewhere in my line.  I had assumed, given that my family was from the north east shore of England, that a Viking raider was somewhere in my past and my genes reflected these facts.  The story about the insect crystallized a new thought in my head and now that I have thought it through I can prove that our rape culture is part of our history for thousands of years.  Proof.  It is not something to be proud of.

You can see the results of generations, thousands of generations of raping in the world today; you always could, it is just no one had connected the dots for you to see.

Here goes.  

When you look out in the world you see people and there are certain attributes that would make people more likely to survive in the wilderness.  And when you look out in the world they are not there, they are unbalanced.  There are many old reasons why things exist the way they exist, but they are also reasons that are easily dismissed.  

I am a man.  I am 6'3" and inch taller when stand tall.  I am barrel chested and if I lost the gut, I would make most bouncers sweat.  I have never been to a gym regularly and have never tried to make muscle, but I have it in spades, I can lift three hundred pounds easily.  This makes me a real power house and by the law of the jungle, I should be able to do anything I want.  But, it should not be that way.  Evolutionarily, I do not make sense, the only thing that I am good for in this body is beating off other males and raping any woman I can find.

Evolutionarily, smaller is more efficient, if anything women should be bigger than men so they can survive childbirth more easily, but we see the opposite.  On average women are smaller and frailer than men.  In our past, collectively, big men could mate with more women than small men.  Big men could force more smaller women than big women, so small sized women were selected over stronger women.  

Men need to be stronger to kill and get meat.  This is untrue.  Hunter gather societies gathered more than they hunted and in any case human hunters were successful not because they were bigger than their prey, but because they could outlast them and because they worked cooperatively.  A single big man could never kill a mastodon, and while a single man might be able to kill a deer, keeping the lion from taking it, would never happen.  Only large numbers could take down large prey and only large numbers could secure prey. Size does not matter.

Large men make better soldiers and can protect more people.  Larger size is more intimidating, but larger people eat more, larger people need more to live.  I don't claim to know what the ratio of size to resources, but I know that more small people are better than fewer larger people. For any task.  On big person can lift more, but two smaller people can lift more than the one person.

Any way you look at it, it comes down to large sized males are less fit evolutionarily than smaller men, unless there was another selective pressure, historically, rape.
