This means that a male can father many more offsprings than a female can in her lifetime.

Even though monogamy..as a modern concept..is more prevalent, it is more often than not, serial monogamy.

But. Because. Evolutionary hardwiring.

Women want males to be providers because males can impregnate multiple females at the same time. Without being a bonded pair, or the resource costly job of raising offsprings would not be a shared endeavor. Bringing forth children takes a physical toll on a woman in more ways than one. It doesn't cost men anything other than ejaculation to create offspring. So women give birth. Men provide.

Of course, society has changed so much since cave men days, but our wiring probably hasn't..

Tying back to original topic...when women provide for themselves, what is the role of men? Perhaps our free floating relationship matrix without the need to be bonded pairs to bring forth offsprings is the reason.

Birds spend a lot of energy while flying..they have hollow bones and have a high metabolism. They expend a lot of energy just to exist. They migrate.

Mammals hibernate. They know how to conserve and regulate metabolism. Their energy needs are less expensive. Maybe that's why birds are monogamous and many mammals have harems.

As mammals, the human animal is already living within a moral but artificial construct of monogamy. Female apes share responsibilities to raise their young communally. Monogamy is an evolutionary disadvantage. It conserves energy and resources. It promotes kinship.

Human apes don't. Right or wrong, that's different. But we don't. If women can provide for themselves and have control over their reproductive freedoms, why do they need free range men anyways? The Y chromosome is supposedly composed of junk DNA.

This is bit of a ramble, but I would like to think it made at least some go 'a-ha'!
