Why is patriarchy dominant?

I've gained an interest in feminism recently, and have been doing lots of reading on the subject. One of the questions I've thought of that hasn't been answered is this: For what reason is patriarchy the dominant mode of societies around the world? I was wondering if you guys knew any answers or material on this question.

Nobody really knows, but here is at least one hypothesis:

In their book 'Sex at Dawn', Ryan and Jethá argue that patriarchy is a consequence of humans moving from hunter-gatherer social structures to agriculture. In short, the argument is that needing to defend patches of land (a foreign idea to nomadic hunter-gatherers) drove demand for a warrior class, which men excelled at. Men thereby gained social power, which then had further structural effects on society.
