Do we innately conceal our genitals?

Posted: 29 Jun 2018 01:27 AM PDT

Clothing seems to cover the genitals across all cultures.

Reading on Wikipedia, it seems that covering the genitals began at most 72,000 years ago, as remains have been found with clothing from that time. But for all of recorded history across all cultures that recorded history, clothing that covered at least the genitals was considered natural and normal for everyday life.

Glorious Wikipedia claims, in the article history of nudity, that nudity was the norm in "warmer climates" until the introduction of Islam or Christianity. It claims that nudity is still the norm in "Mursi, Surma, Nuba, Karimojong, Kirdi, Dinka and sometimes Maasai people in Africa, as well as Matses, Yanomami, Suruwaha, Xingu, Matis and Galdu people in South America". Upon further examination all of these claims are sourced to Active Naturists, "what if nudity were a norm?" (sic), a nudist blog post scholarly journal, surely. I'm sure it's a great source, since it's cited on Wikipedia and all, but it seems to stake its claims that nudity was the norm among those peoples on questionable grounds:

  • Artwork and statuary, mostly from the ancient Greeks, who notably liked naked young guys and also are not any of the people listed
  • Photos of African boys/men during nude initiation rites
  • Quotes from noted racist Henry Morton Stanley about the clothing habits of "the naked savages" during appeals to the British to claim African colonies and convert the natives "to the wearing of clothes"
  • Photos of nude Nuba men presented with scarcely believable context; perhaps that is their everyday habit, but other sources suggest that the nudity is related to traditional Nuba wrestling
  • Some photos of Amazon native people presented with extremely questionable context
  • Various other photos of native African and Amazonian people, which Active Naturalist gives me no reason to believe are typical
  • A ton of photos of native African and Amazonian people who are clothed in their genital region, but presented as if they are nude Any further Googling just gets me shitty pop-psych articles like "if we were nude guys would be horny all day duh".

Are there any human cultures where the genitals would be exposed in daily activities? Do we know why we prefer covering our genitals?

Did Paleolithic diets lead the human jaw and face to develop a different shape?

Posted: 29 Jun 2018 05:59 AM PDT

According to Wiki, "After the advent of agriculture over 10,000 years ago, soft human diets became the norm, including carbohydrate and high energy foods. Such diets typically result in jaws growing with less forward growth than our paleolithic ancestors and not enough room for the wisdom teeth."

Why does nitrogen break the octet rule in NO, while oxygen do not?

Posted: 28 Jun 2018 01:44 PM PDT

So NO has 11 valence electrons. The oxygen fills up all 8 of its electrons, while nitrogen gets the radical. Why doesn't oxygen get the radical and nitrogen with 8 e-. I get that it breaks the octect rule because it has a odd number of valence electrons.

Which substances or foods create metabolites that can be detected for extended periods of time?

Posted: 28 Jun 2018 08:38 AM PDT

I was recently reading about alcohol and how even after your body has completely processed and excreted the ethanol, it creates metabolites Ethyl Palmitate and Ethyl Glucuronide that can be detected in hair for up to 90 days.

I am curious as to why these metabolites hang around for so long and also which other substances and/or foods have metabolites that can also be detected for any extended period of time.

For example, if I consumed caffeine how long would you theoretically be able to test for it if you wanted to? What about broccoli, or carrots etc?

Are there any factors that cause metabolites to stick around longer, or certain groups of foods?

I hope my question was clear enough and not too broad scoped.

Thanks!

How important is visual data of lip movements during language acquisition? Do people blind from birth pronounce words as properly as seeing people?

Why is it that when you cramp flexible circles together you get hexagons (honeycomb) specifically, and not any other shape?

Posted: 29 Jun 2018 03:57 AM PDT

What is the mathematics going on? I'm expecting some equation that links pi to the circumference of a circle and a constant, 6, or something like that.

Do snakes live together? (Garter snakes)

Posted: 28 Jun 2018 04:54 PM PDT

There is a rock near my house with a hole in it and everyday I walk by and there are 2-3 snakes living together in the hole. It seems like they're friends or a family or something. The biggest snake stays at the exit, male garter snake, then when I approach if I get too close he will slither out and run off. Then when you look inside there is at least one other snake that appears to be female. Do snakes live together and are they really smart enough to devise this survival strategy? Is this common?

Extracting and burning fossil fuels has a well documented effect on the climate and atmosphere, does extracting from fossil water reserves have a similarly significant impact on climate, atmosphere, and global water cycles?

If you swallow something, would you get the same nutritional value if you chewed it?

Posted: 28 Jun 2018 12:10 PM PDT

Probably a dumb question, but I've always wondered this.

If a woman who is pregnant gets or has cancer, is it possible for the child to get cancer as well?

Posted: 29 Jun 2018 04:48 AM PDT

Unless I understand cancer wrong, I thought that, since cancer can spread, it could potentially spread to the child.

In particle accelerators, could we handle charged dust-sized particles the same way we handle ions, protons and electrons? How much energy could we potentially impart to a dust-sized particle this way?

Why is there much more of certain elements compared to the elements next to them on the periodic table?

Posted: 28 Jun 2018 09:39 AM PDT

My basic understanding of how elements are formed is that the heavier the element, the more energy is needed to create the conditions for it to be formed. So I would expect the occurance of elements to be pretty much descending the heavier the element is. But, looking at the webpage sourced below for the universes makeup, that's not so. For example, there's a lot more carbon than boron, much more oxygen than fluorine, and much more iron than maganese or cobalt. Why is this?

Can multiple parallel procedures be simulated as a one?

Posted: 28 Jun 2018 10:41 PM PDT

If you have an abstract system which runs a number procedures, naturally with possibility of being out of sync, is it possible to emulate the evolution of the whole as a single procedure. I just go idea that one could maybe encode the whole system as an evolution of one-dimensional string. Or does it turn out fundamentally impossible task?

Please grant any notable properties, pros and cons, of such way of structure if you know any.
