Ok, that's helpful information. I'll take your presumptions as is (mating for life, etc).
It seems to me, based upon your stated views, that there is a bit of a disconnect between your view that the only meaning to life is reproduction, and your view that cohabitation (for life) is imperative to successfully raise a child. If we say that the only meaning to life is reproduction, then it would stand that it would be more beneficial for the male to have as many children as possible to pass down his specific genes, which as many females as possible. The downsides to childrearing is, basically, solely on the female. The male, once coitus is complete, has little incentive to stay with the female, especially after her childbearing years, whereas the male is virile 20-30 years after a female is no longer capable of producing a child. It's a simple numbers game - is it more beneficial for the male to father one child with one wife and take the risk that the child will die unexpectedly, or have multiple children with multiple females in different areas / situations, thus increasing the chances that at least one of those children will be able to successfully carry on his genes?
That isn't even getting into the issue of one male with multiple females, which means that the male can further extend his reproductive ability while providing for multiple females / children, while still "mating for life" with each of his wives, and ensuing that there are multiple females around to care for his children.
