Please take my comment as a truism about evolution rather than women in particular. The extremely superficial explanation is my view of one strategy among many.
Primitive strategies are none the worse for being primitive: though no guarantor of success, they're often adequate. thus the number of citations of a science paper is not a direct reflection of its quality, but not irrelevant either. I was surprised to discover that market traders, far from being tight-lipped about their strategic overview, spend a lot of time calling each other up when things were slow to ask what their competitors thought of the day's financial 'weather'. Google's Pageranks are similar. And so on.
It is true that a fairly non-promiscuous person will likely be a better parent and thus a desirable match. Nevertheless, some competitive genes don't hurt. Also commitment after experience is more interesting than commitment by default (see daily YC thread on how 'Windows users only like it because it came with the computer they bought').
