Genetically, it's best if men are promiscuous and women chaste (Dawkins, Blackmore). That's not to say that society should be built on such lines; only that such behaviour has the best chance of passing on your genes to the next generation.sackett said:Perhaps your observations about the difficulties of second wives and their children partially answer the question of why many countries enforce monogamy: life can get miserably complicated when a man is allowed to take on multiple family obligations. Let's face it, an awful lot of guys are irresponsible pr**ks who shouldn't be reproducing themselves even once, let alone two or three or seven times.

We're talking genetically here. When the object is to pass on to the next generation as many genes as you can, women should be as picky as possible, so that the mate she does finally choose has the best genes (for running, height, athleticism, etc.), which then go into the next generation. Child rearing doesn't come into it.neutrino_cannon said:I had certainly heard that, but I'm not sure if it makes sense. I would reason (this not being my own reasoning) that:
-A female with multiple partners has more resources to draw from, assuming that's fine with all the guys. This could be a biggie.
Corrolary: The offspring of a polyandrous construct would have more parents, which could be a good thing.
-A female with multiple partners will increase the number of genetic combinations in the next generation. This is a good thing, assuming that genetic diversity is good (a fairly sound assumption I think).
-A female with multiple partners is not vulnerable if any one male is an underperformer. Assuming that the males are the providers of course, a female with multiple providers does not have to rely upon a single and possibly unreliable provider.
Corrolary: She can have the other guys thrash anyone who doesn't behave well enough.

But that's not relevant to passing on one's genes to the next generation. Certainly, one reason women play hard-to-get is to gauge a man's likelihood to commit himself and stick around after the child is born, whereas a man wants to move on and spread his seed around as far as possible. From which standpoint, the father doesn't hang around long enough to see if the infant survives.neutrino_cannon said:It most certainly does when you account for infant mortality as a function of availible care.

Actually, a male with genes for conning a more caring male into caring for his (the con artist's) children will pass on more of his genes. That's how cuckoos work.neutrino_cannon said:A male with genes that "make" him commit to relationships with better availible care for the children will tend to have those genes passed on, since more of them will live. Similarly, polyandrous relationships that utilize males to raise children and reduce mortality will produce more offspring. If there's any genetic component to that behavior, it will be selected for. .

There are a variety of tricks that selfish exploiters use to make sure that they are the ones to benefit, normally at the expense of others. Dawkins describes this phenomenon in depth in The Selfish Gene. (Highly recommended.)neutrino_cannon said:Hmmm... parental parasitism.
I can't imagine it working long on a grand scale within a species.
