I n a recent Guardian articleSimon Copland argued that it is very unlikely people are born gay or presumably any other sexual orientation. Scientific evidence says otherwise. It points strongly to a biological origin for our sexualities. I Is homisexuality genetic argue that understanding our fundamental biological nature Is homisexuality genetic make us more vigorous in promoting LGB rights.
Three gene finding studies showed that gay brothers share genetic markers on the X chromosome; the most recent study also found shared markers on chromosome 8. This latest research overcomes the problems of three prior studies which Is homisexuality genetic not find the same results. Gene finding efforts have issues, as Copland argues, but Is homisexuality genetic are technical not catastrophic errors
Is homisexuality genetic the science.
Is homisexuality genetic of these genes has a small effect on the trait so do not reach traditional levels of statistical significance. In other words, lots of genes which do influence sexual orientation may fall under the radar. But scientific techniques will eventually catch up. In fact there are more pressing problems that I would like to see addressed, such as Is homisexuality genetic inadequate research on female sexuality.
Genes are far from the whole
Sex hormones in prenatal play a role. For example, girls born with congenital adrenal hyperplasia CAHwhich results in naturally increased levels of male sex hormones, show relatively high rates of same-sex
Is homisexuality genetic as adults. Further evidence comes from genetic males who, through Is homisexuality genetic, or being born without peniseswere subjected
Is homisexuality genetic sex change and raised as girls.
As adults these men are typically attracted to women. The fact that you cannot make a genetic male sexually attracted to another male by raising him as a girl makes any social theory of sexuality very weak.
Genes could themselves nudge one towards a particular sexual orientation or genes may simply interact with Is homisexuality genetic environmental factors such as sex hormones in the womb Is homisexuality genetic to influence later sexual orientation. The brains of gay and heterosexual people also appear to be organised differently.
For example patterns of brain organisation appear similar between gay men and heterosexual women and between lesbian women and heterosexual men.
Differences in brain organisation mean differences in psychology and study study show differences Is homisexuality genetic cognition between heterosexual Is homisexuality genetic gay people. Thus gay differences are not just about who you fancy.
They are reflected in our psychology and the ways we relate to others. The influence of biology runs throughout our sexual and Is homisexuality genetic homisexuality genetic lives and those differences, that diversity, is surely to be celebrated.
Some writers tend to wave off the scientific evidence by urging us to look to the history of sexuality or
Is homisexuality genetic that homosexuality is a social construction cue Michel Foucault and the like. But these accounts are mere descriptions at best and not scientific
Is homisexuality genetic. Social Is homisexuality genetic accounts generate no hypotheses about sexual orientation and are not subject to systematic testing.
So why should we take their claims Is homisexuality genetic Social constructionism and postmodernist theory question the very validity of empirical science in the first place. Is homisexuality genetic makes it no better than climate Is homisexuality genetic denial.
Change is widely used to argue against biological explanations. This is false because it is our biology that allows us to learn, respond to socialisation, and helps generate our culture.
So showing evidence of change is not an argument against biology. There is indeed some fluidity in sexuality over time, predominantly among women. People may change the identity labels they use
Is homisexuality genetic Is homisexuality genetic they have sex with but sexual attractions seem stable over time.
Remember, sexual orientation is Is homisexuality genetic homisexuality genetic pattern of desire, not of behaviour or sexual acts per se. It is Is homisexuality genetic a simple act of will or a performance. We fall in love with men or women because we have gay, straight, or bisexual orientations and not because of choice. They worry more about this than the consequences of choice or environmental explanations, which are without risk either.
But clearly none of the direst predictions have materialised. Sexual minority identities have not been medicalised nor has Is homisexuality genetic been any genetic testing. So should the causes of sexuality influence how we view
Is homisexuality genetic minority identities?
causes of a trait should not influence how we see it. But the science shows us that sexuality has a biological basis: The biology of sexuality diversity tells Is homisexuality genetic world to deal with it. We are who we are, and our sexualities are part of human nature. It reminds me of something Noam Chomsky alluded to: He studies the biology of sexual orientation and the implications for mental health and is the
