@WiringTheBrain Probably not (homosexuality likely pathogenic, at least for men) http://www.unz.com/jman/greg-cochrans-gay-germ-hypothesis-an-exercise-in-the-power-of-germs/ …@sapinker@sciam -
.
@JayMan471@sapinker Just because conditions that are selected against persist does NOT => high-risk genetic variants persist. They recur. -
.
@WiringTheBrain Not at 3-5% prevalence, no. Most genetic load syndromes top out at 1%.@sapinker -
.
@JayMan471@sapinker Evidence for partial heritability of sexual orientation is strong and consistent http://www.wiringthebrain.com/2014/03/gay-genes-yeah-but-no-well-kind-of-but.html … -

@WiringTheBrain Heritability of male homosexuality is not zero, but it's quite low (0.22). Co-twin of gay twin usually straight.@sapinker -
.
@JayMan471@sapinker Yes, so it's partly genetic. (And I'd say partly developmental). And no reason (like, at all) to invoke a pathogen! -
.
@WiringTheBrain Plenty of reason to invoke a pathogen. Developmental noise doesn't make sense: https://westhunt.wordpress.com/2013/01/12/homosexuality-epigenetics-and-zebras/ …@sapinker

@sapinker Data can't 'determine' this without an explanatory theory. Especially of how the determining force overcomes human universality. -
Isn't this just about development of biological hardware that creates sensory experience of hunger, thirst, lust?
-
Yes. And human universality could allow you to change. (But might take 1000 years.)

.
@mgoldingmd@TheCrookedMan@sapinker Maybe—though it must depend on what knowledge is available—but the *data* are silent on that issue too -
Is the claim here that human universality allows individuals to choose sexual orientation?
-
.
@craig_labenz@mgoldingmd@TheCrookedMan Well, it's that nothing inborn prevents such a change. Like 'choosing' to have faith in Zeus. -
This seems *very* counter to my own personal experience, and the reported experiences of others.

In theory, yes, I could run off w the mailman tomorrow, but I can't seem to make myself want to.

unfortunately in Europe, a lot of blankslaters are on the left too.

@sapinker & post-natal does not equal "social" in context. I wish Hamer & Bailey would address the pathogenic hypo, if only to debunk. -
Bisexuality as practiced in Ancient Greece Rome and Afghanistan today is genetic? How so?
-
Important to keep in mind that prenatal/biological doesn't necessarily mean genetic.
-
Then the mother is at fault? Seriously, seems to me myriad factors are going to be involved.
-
There's little evidence for parental/maternal influence. Divorce rates would have tracked, for one thing.
-
No, I mean if sexuality is fixed and innate, then it must be prenatal: meaning, (a) genes, (b) mother.
-
Biological doesn't necessarily mean innate. Pathogenic transmission could occur later.
-
Whoa, are you suggesting that the mother could pick up a "gay germ" while cleaning the cat box?
