SQ - As you said, it's helpful to lay out where we are coming from, so here is where I'm coming from:
I believe in human rights - an end to discrimination and oppression, the right to survive and thrive for all people. This is a moral ideal and non-negotiable.
I think the world is governed by natural forces and that all species evolved through natural selection. This is unavoidable, but not the basis for morality.
To better understand ourselves and our societies (and change them) we need to understand the biological basis of human behavior,
This is NOT the same as the same as the idea that nature provides a moral template for how we should be. 'Natural' does not mean good.Nor is it biological determinism. We don't have to live as our stone age instincts tell us.
While there is a conflict between the species we evolved to be, and the people we want to be, I don't think there is a conflict between studying and understanding humans as an evolved species and wanting to achieve equal human rights.
There is nothing that science can tell us about the relative tendencies of men and women that would justify harrassment, discrimination or abuse of anyone.
The conservative idea that men and women are completely different and suited to different roles in public and private spheres is clearly a crock of shit. For any task - domestic or public there are men and women who could do it, and where there are measurable differences in the spread of abilities they are marginal and not enough to explain male dominance of the public sphere.
So there is nothing to fear in studying differences robustly and nothing odd or ideologically suspect - since sexual selection is such a HUGE factor in human evolution. (other than people leaping to the wrong conclusions or using science to shore up predjudice - but this is not a reason not to study this stuff - just a reason to understand it better).
relatively minor inate differences can be amplified by social structures and attitudes. One of the most important inate differences I think is men and women's relative willingness to step out of public life (whether we are talking hunting for food or running for president) in order to care for their children when young.
From an evolutionary viewpoint this makes sense -- when two people have a child together the male has more to gain by continuing to hedge his bets putting effort into gaining public status (to win more women, more resources, more children in the future) and the female has more to loose unless she puts every effort into protecting the survival of the child she already has (it is definately hers, and she has already invested 9 months and risked her health to have it).
We still see the same trends today in that women tend to marry older men with greater status than them (higher earning) and then take a greater share of domestic responsibility after children.... and all the consequences of that...
These kind of biological urges made some sense in our prehistoric past when survival and paternity were uncertain. But they don't work anymore. Understanding that they are natural doesn't mean giving into them or giving up on feminism.
Happy Xmas one and all!
