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.

-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.


The Cinderella Effect

Are step-parents more likely to abuse and kill you?

Well according to evolutionary psychologist it seems this is so. Its explained using ‘the Cinderella effect’. Basically what they think is as parents wants to pass on their genes so they are more likely to care for their biological children more than they are to their non-biological children (step children). So in effect what they are trying to say is that step parents are more likely to abuse children that are not biologically theirs. Clearly this seems to me like a ridiculous conclusion. Yeah it has evolutionary logic behind it, but I think humans have minds that are more sophisticated than that..

This theory has been falsified by Temrin, Nordlund, Rying and Tullberg (1965-2009)who looked at data from Sweden on violence. Their results showed 27 homicides committed in step families, 13 stepchildren were killed, 13 biological children, and 1 case of both. This shows that mistreatment of children is not more likely in a family who are all biologically connected, but can happen in any type of family. Even so the research done may not be a clear representation of the general population as the data used was only extracted from Sweden, and also they only looked at homicide as part of their numbers. Not any other kind of abuse. The research lacks reliability and so needs to be replicated to ensure the findings are true in all situations and places.

More research needs to be conducted in this area though I personally think this theory is not correct because there are many cases of people looking after step children and treating them the same. As well as this there is the fact that people adopt children and raise them well alongside their own biological children. This shows that people are not just hugery to pass on their genes as they have care for others aswell.
