Firstly, I apologize if this is against the rules. I will delete my post if it is (I know the rule about evolutionary psychology and I agree with it, which is actually why I am asking this). I am coming to this place because it seems my field and profession have failed to address it.

As a psychology student, I studied evolutionary psychology, but it turned out to be a simplified introduction to evolutionary biology, as our professor was an evolutionary biologist and not a psychologist. During my studies and that course, I noticed that evolutionary psychology theories are mostly unconfirmed and often cannot be confirmed.

This is why I wanted to come here to get a first insight into how that could be changed. I do not plan on having this as my only source of information, of course, but I guess it's a good starting point since I have basically zero knowledge in the field.

So, what should methodology, conjecture, and hypotheses be like in order to have more than just untestable hypotheses?

Also, I am aware that methodology is far more complex and that it cannot be compressed into one Reddit post, as it plays an important part during the study. So, I would be thankful if you recommended some literature I could check out.

I understand why animals are mostly either male or female, almost never both (with some exceptions), but I don't really understand why some flowers have only male structures or only female structures. Let me explain.

Some flowers/plants, for example, have both stamens and carpels. But some have only one of those and need a pair in order to produce seeds. Why is that, since having both seems like a huge evolutionary advantage?
