I'm sorry to disappoint you, but your "female primate's" description begs the question, what make you think that we won't prefer to be like bonobos instead of chimps? XD

Sorry, but if you read history, whenever a woman has had a shot at power, she has take it. The more recent example Elizabeth II. But she is not an exception. From Hatshepsut to Margaret Thatcher, there have been women that have tried to win power despite the obstacles that came with being a woman.

I think that you are trying to erase centuries of history and examples of women wanting power to try to fit your "biological determinism" model. But the truth is that if it was in our biology, one century wouldn't be enough for women to make advances to vote, go to university in higher numbers than men, join the workforce, become politicians, etc. No species evolutionate in just one century. But what do you know? In just one century, once removed the obstacles to education and political participation that prevented women from seeking power, there you go, women seeking power. Or do you claim that Hilary Clinton is not ambitius? XD

I'm afraid that the evidence is that women are as ambituos as men. You are the one trying to justify that women were denied rights by claiming that they didn't want them (even if they in fact fought to get them). Please, read more history. You'll find plenty of examples of women plotting for power with whatever resources men couldn't take from them.

You might want to look again at your theory, because it doesn't hold if you consider that in just one century women have changes habits. You confuse "size" with ambition and those are unrelated things. After all, Napoleon Bonaparte was famously short or to put it in your words "has a smaller size" and that didn't prevented him from winning battles and getting power, right?

So if your "theory" is that women didn't wanted power because their size, let me tell you, it is absurd. Size is unrelated to ambition and women have always wanted freedom equal rights and power. We were just denied because as you pointed out, our size make it difficult to assert our rights. Which leads me to the original point, if by just having sex women could have got power in the past, they would have get it. And Marilin would have been president instead of singing happy birthday to one. XD
