Evolution And Homosexuality

Evolution psychologist see men as sex crazed individuals who care only for passing on their genes. So I was thinking maybe this could explain homosexual behaviour.
As part of sexual selection men are involved in more intense intersexual selection as women are choosey when it comes to picking a mate for the following reasons.
-Their Eggs are limited whereas sperms are not so they want to spend time looking for the mate with the best genes that will help to make an offspring that will have the best chance of survival and ability to attract the opposite sex. Females also spend more energy producing every single egg. Males don’t need to do this to produce sperms, I’m guessing it’s pretty easy to make sperms…well easier than making an egg because women can only produce one every month whereas men can produce sperm whenever and however often.
-The number of eggs drop as the female contributes in more sexual activities; whereas the amount of sexual activity a male takes part in doesn’t make any difference to their sperm count.
-Cost of pregnancy- Females go through 9 months of pregnancy meaning they can produce a limited amount of offspring’s in their lives and so the males get fewer opportunities to be with a female. Males on the other hand can produce an unlimited amount of offspring’s as they are only needed for a few minutes to produce sperm.
-More time spent caring for the offspring (maternal investment). They have to breastfeed the baby for at least 3 years where as males don’t need to do this.
All these reasons make women a lot more picky towards sexual mates because they can reproduce a limited amount of times so they’d want to pick a mate that is the healthiest and attractive so that those traits can be passed on to their offspring.
Men are more promiscuous, seek more sexual encounters and have a bigger appetite for sex and so they try to impregnate as many women as possible…but this is not always likely because they might be unable to attract willing sexual partners which leads us to the evolutionary prospective of rapists, but that a whole different blog that I need to write.
I’m not claiming to be an experienced psychologist or some sort of researcher or anything but I think that perhaps from an evolutionary view the reason some people are homosexual is because people get the feel that females are a lot more choosey when it comes to having sex and men aren’t. So if they are able to easily engage in sexual activity with another man then there is no need to have to work really hard to get a female. Also they do not have to take part in intense intra sexual selection, which will enable them being able to avoid aggression from males and therefore promote survival.
Research clearly shows that gay men have a lot more sex and lesbians have less. Symons (1979) found from a study that 25% of gays in San Francisco had more than 1000 sexual partners whereas lesbians rarely had more than 10 sexual partners in their life time, they seem to be more preoccupied with evolving a long term relationship.

LIMITATIONS.
-They don’t actually come to make any offspring’s so this may not be valid explanations for homosexuality. However many homosexual couples may make use of surrogate moms. This allows them to get the best out of the position. Gay men; lots of sex and offspring’s with their genes. Lesbian women; sex partner that they have taken time to choose and an offspring.
-They know there’s more to a relationship than sex, so therefore to saying gay men only want sex in a relationship is not right.

Homosexuality

The argument about homosexuality being a life choice has been going on for years on end now. To be frank I have no idea why this is so. Let people be who they want to be.

I notice people either saying that it’s either completely genetic or social (nature nurture) I personally think that it’s silly to say its either one or the other because its probably a mixture of both. Though to say it’s a life choice is ridiculous. No one wakes up one day and decides they will be a homosexual.

I’d just like to say if homosexuality was learnt or if it was a choice then why do we have gay and lesbians in more religious countries that sees homosexuals as being criminals? They get hung and stoned to death! Why in the world would anybody ever want to choose a life style that came with treatment like that?? It makes no sense to me. So think again before saying it’s a life choice.

‘Hamer et al. found that the gay men had more gay male uncles and cousins on the maternal side of the family than on the paternal side.’ I would link this to the finding by researchers at UC Santa Barbara and Uppsala University in Sweden who have come to realize that sexual orientation can be decided through epi-marks. These are switches that are passed down from the opposite sex parent…
Epigenetic markers are “an added layer of information that clings to our DNA,” and regulate the expression of genes according to an external trigger. The external trigger here I’m saying would probably be the uncles and perhaps the family environment in which they were ‘allowed’ to be gay.
