We need both genders -- neither can be discarded, and insisting that the two genders are so similar as to not have any unique properties or advantages is the same as discarding them.

I have a simple thought experiment for those who have a strong impulse to downvote the parent comment (and doubtless my own comment): Imagine the discussion here were, say, a study that illustrated men naturally resorted to forming factions and solving disagreements with violence, and someone commented, “No, it’s 100% society, not innate whatsoever” and then someone replied to that saying “no, while individual variation is of course very real, there is some evidence that the general trends that inform some of our stereotyped intuitions of gender are based in biological fact.” Would you be quite so quick to mash the down arrow? … Perhaps. It’s a discussion fraught with a lot of charged emotions, and we collectively are not so good at dealing with points of view contrary to whatever we want to believe.
I don't know anybody who would argue that gender has absolutely no biological implications. But to suggest they tell us something about how society should be structured is the naturalistic fallacy, confusing is with ought.
As an example, illness and death are natural. But that doesn't mean that we should just shrug and say, "Oh well, tuberculosis is natural, so we should just accept it." The natural details of death should certainly inform how we fight it. But they can never tell us we shouldn't.
For those interested in how much this varies across species, I heartily recommend Dr Taiana's Sex Advice to All Creation: http://www.amazon.com/gp/product/B00846X144
It's a great and funny book on the biology of gender and reproduction, written as an advice column.
Growing up in the midwest, I mistook a lot of what people got up to as essential facts of human biology. But after 15 years living in San Francisco, I've come to realize how much of that is purely socially constructed.
