I don't think I was constructed to be monogamous. I don't think it's the nature of any man to be monogamous. Men are propelled by genetically ordained impulses over which they have no control to distribute their seed into as many females as possible.
I think romantic love evolved to enable you to focus your mating energy on just one individual at a time, thereby conserving mating time and energy.
The preoccupation with the choice of a mate both by male and female I regard as a continuing echo of the major selective force by which we have evolved.
By separating the function of adaptation from the function of maintaining the integrity of individual genes, sex allows much greater diversity while still keeping genes whole. Sex is not only fun, it is good engineering practice.
There are some viviparous flies, which bring forth 2,000 young. These in a little time would fill the air, and like clouds intercept the rays of the sun, unless they were devoured by birds, spiders, and many other animals.
From an evolutionary point of view, sex is really just a reward mechanism to encourage us to pass on our genetic material.
There's no biological reason why a man shouldn't just try to have sex with every woman he meets - all of them get pregnant and your genetics are winning.
Mating Strategy is influenced by the cardinal fact that women have more at stake in sexual activity than men, because of the limited age span in which they can reproduce and the heavy investment required of them with each child conceived. In courtship women consistently emphasize commitment of resources and material security.
Thus mating of females was strictly along the lines of paternal song.
Sexual reproduction exists solely as a means to defeat parasites. By mixing male and female genes, sex produces offspring not exactly like either the male or female - making each generation different from the last, and presenting a moving target to intruders intent on compromising this system. ... Even with this variation, parasites continue to pose a threat... and parasitism evolves and moves through any system - not just living things. The less variation there is in a system, the more readily parasites will evolve to infest it.
Genes which allow females to be less inhibited leave fewer copies of themselves than genes which persuade them to remain highly selective. Among males, the best strategy is exactly the opposite one. The maximum advantage goes to those males with the fewest inhibitions. "Love 'em and leave 'em" is not so much a nasty peice of male chauvinist piggery as an accurate reflection of biological reality.
If you put out 20 films, you hope that a number are successful. It's like human reproduction versus frog reproduction. Frogs produce thousands and hope a few succeed. Humans don't produce many babies but put a lot of energy into them, which is kind of where we are. They still don't always succeed, but you try a lot harder.
Cheese crumbs spread before a pair of copulating rats will distract the female but not the male.
Women do not avoid fighting because they are dainty or scared, but because they have a greater stake than men in staying alive to rear their offspring. Women compete with each other just as tenaciously as men, but with a stealth and subtlety that reduces their chances of being killed or injured.
Because men, compared to male chimps, have such relatively small testicles (large testicles indicate a species where many males mate, one after the other, with the same female), we might guess that promiscuous societies were uncommon in the immediate human past.
We are finally driven to monogamy not by morality but by exhaustion.
No practical biologist interested in sexual reproduction would be led to work out the detailed consequences experienced by organisms having three or more sexes; yet what else should he do if he wishes to understand why the sexes are, in fact, always two?
If a hamster has too many babies she knows she cannot carry, she not only abandons them, but she eats them. That means she doesn't have to go out and hunt for food for herself.
Mama grizzlies mate later than other bears. They have two cubs instead of four. They wait four years - about twice as long as other bears - between having cubs. And after they're pregnant, if winter is hard or their health is not good or the food supply is uncertain, they re-absorb the embryo into their body.
A zygote is a gamete's way of producing more gametes. This may be the purpose of the universe.
I am like a praying mantis, after I have sex with a guy I will rip their heads off.
