That's my point. That culture can suppress biological need. We all need to belch sometimes, but some cultures have made it "rude", so we refrain from doing it whenever possible. It's not something we can always control however, and that is the key difference. I'm proposing that the legs are a vestigial trait,…

never said it wasn't rude. belching and farting are rude as well, doesn't mean they aren't a result of a biological process.

not even close to what i said. bye felicia.

Sitting with your legs wide is rude.

sitting also invites it. if you choose to sit next to some, they see it as an invitation to open communication. can't tell you how many time's i've sat next to someone and they try to convert me to christianity. speaking is not the only instigator

again, it's an unconscious choice. evolutionary development is not generally a willful choice

Um, why would fat be stored in the testicles? The additional mass is typically stored in the gut and thigh regions in men. Larger mass - more heat generated. Increased heat production, more need to keep them open.

Then your problem isn't with people who keep their legs open on on the bus; it's the potential that speaking to someone invites harassment. You're just as likely to get harassed by choosing to sit next to a creeper who happens to have his legs closed. If you're worried that a guy with his legs like that is going to…

Well there ya go. While there are some biological differences between the average Brit, and American (keep in mind we're not just talking about white males here), the cultural differences are much different. Now I'm not saying biology influences culture, just some aspects of human behavior. Some of the main…

I don't care if it's a natural urge because it's a unnecessary one

I didn't imply a need for increased fertility to begin. I said it's a vestigial behavior designed to keep the testicles cool, because having optimal sperm production was important to our ancestors when they didn't have fertility doctors to help. If there's any implications of an importance to increase fertility, it…

That's great; where though.

First point, not an argument.

such as where? until recently i don't think many paid attention

First statement, yes. It's quite rude, and I feel that it is a behavior that's been bred into us. Yes, it is the biological impulse to keep the testicles cooler than the body.

Clothing is mostly a cultural construct, and has little to do with biology.

Men produce sperm. Sperm is optimally produced at a lower temperate inside the testicles. Keeping the legs open reduces the temperature of the testicles.

Favorite Silent Hill "thing".

Why is it considered taboo in some cultures for women to express their sexual desires?

Yes, I agree, there's no reason that we can't close them. I'm not saying that if you have a penis you can't or shouldn't close your legs. All I'm saying is that the default subconscious behavior may be to keep them open. Sperm take several weeks to reach maturity, so I'm not sure what you're getting at with your…
