Guess what I learned in Bio today about gay people, mommy!

So my biology instructor decided to spend today's lecture discussing biological aspects concerning specific propositions up for ballot--the energy one, the animal cruelty one, and the gay marriage one

I learned about this briefly in intro psych, but I checked it up in my neuro book (homosexual behavior is indexed, doncha know!)

There are many interesting tidbits, but it's the INAH-3 section (long writ=third interstitial nucleus of the anterior hypothalamus) of the hypothalamus. It's generally larger in men, but homosexual men tend to resemble women in their size of INAH than men.

As for women, there seems to be a connection to fetal androgen exposure (androgen being a hormone, fetal meaning during development) but this is less correlated and less evidence, so it's more of a trend and less understood (which is saying something, since the INAH-3 difference could, in fact, be CAUSED by homosexuality...)

Other interesting tidbits! Boys with more older brothers, even when separated and raised elsewhere, in a different family are more likely to be gay. So, by having more boys, the mother is more likely to pop out a gay boy. Genetically. Or something. Also, a quote: "Interestingly, homosexual behavior is more common among anthropoid primates - apes and monkeys- than in prosimian primates like lemurs and lorises, so greater complexity of the brain may make homosexual behavior more likely." I found that intriguing, the complex brain and homosexual tendencies association.

*flails like a crazy person* want more random psych/neuro info? XD
