Right. This is not a new theory. It's well known that evolution tends to favor polygamy where females are more selective and males are more promiscuous. What's interesting is that this apparently started after agriculture rather than before. I had previously thought that maybe hunter gatherers practiced polygamy but it faded away as we become more agricultural. Also 17 females to 1 male is pretty absurd. Even if you look at cultures that practiced polygamy in recent history it wasn't to that extent. And even when it was practiced, it wasn't necessarily common except in the very upper class, so the average female to male ratio would have been more reasonable. We can only speculate to what degree this might have shaped our (recent) evolution. That's a huge selective pressure on males to have traits that would lead to them being the local king or whatever they were. And everyone alive today would be descended from those people.

>I had previously thought that maybe hunter gatherers practiced polygamy but it faded away as we become more agricultural. I would have thought otherwise, there is very little incentive for you to labour for the tribe if you have no skin in the game, so to speak. So they would give you a wife otherwise, why fight for them? Why hunt? Why do anything to benefit anyone other than yourself? Since you have nothing to lose, you can even steal from them since no one you care about suffers.

Even if you look at cultures that practiced polygamy in recent history it wasn't to that extent. 17:1 ratio in females vs. males having descendant lines surviving to appear in modern DNA doesn't imply 17:1 female:male polygyny. Heck, the reverse (women having multiple partners, especially a higher-station one with better prospects for having offspring and having them succeed in youth and a lower-station one with worse prospects later, perhaps after the previous one died) could contribute to this, though polygyny is probably part of the explanation.

Agriculture created surplus which meant that someone could feed a larger family. If you are a hunter gatherer you need to be a very good one to support more than one wife, even if you are the chief. With surplus generated by agriculture, spare time can be spent innovating to increase the surplus. Inequal skills in building a personal surplus - whether by conquest, investment or thrift - means that some people get richer. Richer men gain power and are able to not only attract more females but rewrite the rules to make it so. A few generations of this and you change the population considerably.
