More study is definitely required though.
The ramifications could impact our gender wars.
I can see MRA sympathizers concluding that their theories re: dimorphism are justified by this research and feel empowered thereby.
I'd find that a faulty conclusion. Although I see a definite impact from biology and evolution on our relationship behaviors across genders, I don't think that (in our species) these factors outweigh our ability to modify our behaviors via culture. Put bluntly, we should be better than that.
Likewise, I feel that feminists that discount the role of biological and evolutionary factors in inter-gender behaviors are expecting too much. There are some biological imperatives that can't be over-ridden*, such as reproduction, and to expect that all behaviors can be mandated is naive.
That said, we need to give feminists (as an aggrieved class) the benefit of the doubt in compromises.
I'm still gonna shout "Son of a Bitch" when i whack my thumb with a hammer, though. I guess I'll just have to grant myself an indulgence for that occasional sin.
*There are individual exceptions, of course. My family unit is happily child-free. I'm discussing group behavior, not exceptions.
