Vashti -
It's a straight forward question -
Nothing to do with fish fingers.
-evo psych is the idea that inherited aspects of human behaviour and traits were shaped by evolution, and that this can be studied.
Is this compatible or incompatible with the theory of The Patriarchy (= that what we observe in the world in relation to men and women is obviously due to global political system(s) put in place and sustained by men, for the good of men as a group due to their belief in male supremacy)?
I don't think they are.
The underlying assumptions of the theory of The Patriarchy seems to be that: people tend to act in their own self interest, or for their group, based on their beliefs, unless someone else oppresses them.
(which are fair enough assumptions before we understood evolution better - i am not saying they are stupid or anything - they have underpinned much tradition social science and work well on a day to day basis).
Evolutionary psychology says something quite surprising and unintuitive - that human instincts and tendencies that were inherited can not be explained because they were good for the species, the group or even the individual, but because the behaviour they caused led to the spread and perseverance of copies of that gene.
If it is true it means that the assumption that people (unless misled, conditioned, oppressed etc...) tend to act in their own rational self interest or for their group, turns out to be false.
