Did you know?

Fingers prune underwater not because of them absorbing the water or
washing away the oil, but because of an evolutionary trait ca used by the
brain to enhance the grip of your fingers underwater.

Did you know that if you were to take all the elephants in the world and line them up in outer space....... they would all die.

So if I was to throw a corpse underwater corpse acquired for reasons the fingers would not prune?

"Scientists were tipped off in recent years when they discovered that severed fingers didn't wrinkle underwater. This suggested the wrinkling mechanism was controlled by the nervous system, and was therefore some kind of evolutionary response."
User avatar #120 to #7 - pokemonstheshiz (10/05/2013) [-]
probably not, unless it died seconds before. The reaction is triggered via the nerve endings in your fingers. People with nerve damage in their hands often don't "prune."
#127 to #7 - baconfattie (10/05/2013) [-]
When the nerves in the hand or some fingers are damaged, the hand will not wrinkle. That's the proof they got that it's an adaptive measure for gripping in a wet environment.

this is actually an interesting question
User avatar #10 to #7 - ssjkirby ONLINE (10/04/2013) [-]
Trick question.

You obviously have to cut the fingers off before you dump the body to help prevent identification.

Knowledge isn't what makes you smart. Any old fool can memorize the periodic table, the declaration of independence, the map, whatever, with enough time and effort.

What makes you smart is when you take said knowledge and apply it to logic and reasoning to answer and solve issues that you didn't have the answer to already specifically memorized.

***** , do muthafukin grapes become raisins so they could grab **** underwater?
Your finger wrinkle because of osmosis, a type of diffusion, because the water in you cells wants to go to the new, larger, source of water around you, so they leave your body to be with the larger body of water.
#40 to #32 - flyingchink (10/04/2013) [-]

hehe yeeeah
User avatar #131 to #32 - retardedboss (10/05/2013) [-]
That's not 100% accurate. I believe it is because the water in the skin cells has a different concentration of chemicals. Passive transfer moves water along the concentration gradient into your skin. The thick part of your fingertip swells up and wrinkles.
User avatar #139 to #32 - psykobear (10/05/2013) [-]
You got Osmosis backwards...
Osmosis is diffusion of water, or transfer of water from an area of HIGHER concentration to one of LOWER concentration. Osmosis would be water entering the finger.
Also, grapes don't become raisins in water... grapes become raisins through dehydration.

"Do grapes become raisins to grab things underwater." Will be the phrase. Yes. I feel.
#56 - thasmackdown **User deleted account** (10/05/2013) [-]
This really is just a theory, Its a happy theory but to be perfectly honest it is more than likely false, it just happens naturally from osmosis in your cells. Osmosis occurs because of pores in your cell membranes. and this is normally a good thing.

Check other sites and look for a viable answer, this one seems a long shot.

But I wont argue with it as long as we can agree its just a hypothesis.
User avatar #79 to #56 - doctorgolgo (10/05/2013) [-]
Hypothesis yes, but then how do you explain the fact that hands with nerve damage do not wrinkle in water? Osmosis controlled by nerves? That's just weird.
#85 to #79 - thasmackdown **User deleted account** (10/05/2013) [-]
I may also explain this by telling you about how your body actually has processes to try to keep your skin from wrinkling, such as the oils your body produces to keep water from soaking into the pores of your skin.
#83 to #79 - thasmackdown **User deleted account** (10/05/2013) [-]
You can read about that in sights as well, that skin is damaged and more protected from sources than other parts of your skin... Take for example the fact that the bottom of your feet, that you walk on and grow calluses on, does not wrinkle
#87 to #83 - kanedam ONLINE (10/05/2013) [-]
a lot of skin on my body doesnt wrinkle when i take a bath...
#91 to #87 - thasmackdown **User deleted account** (10/05/2013) [-]
A lot of things are happening in your body simply from being in contact with a lot of water that is of a varied temperature. More than I could put with the character limit this site has. So just please, do the research on your own if you find my statement not to your liking, I recommend you look for facts than check authenticity, as a true applied researcher might do.
#88 to #87 - thasmackdown **User deleted account** (10/05/2013) [-]
Could you quit quizzing me on stupid logical fallacies and do research for yourself if you really care for gods sake?

I gave you an example, not the holy bible of wrinkled skin. Blood flow plays a factor into the wrinkles on skin as well, the movement of oxygen and the conditions your skin is under during a shower, how your body reacts in "defense" to foreign substance on your body as it attempts to remain at equilibrium within itself, and NOT at equilibrium with the environment.
#92 to #88 - kanedam ONLINE (10/05/2013) [-]
i didnt ask anything... just saying
#97 to #92 - thasmackdown **User deleted account** (10/05/2013) [-]
You implied a logical fallacy on my comment, because you typed that your entire body does not wrinkle in the shower.

I'm simply telling you that there is plenty of reason for that, just I didn't list them for you.

You should not plant doubt when you yourself don't know the facts, and whether you think so or not, saying something like "a lot of skin on my body doesnt wrinkle when i take a bath..." is quite a cynical statement that will fill others with skepticism. When in reality they should not be buying into the hypothesis that is in this Content.
#100 to #97 - kanedam ONLINE (10/05/2013) [-]
skepticism and doubting is one of the core foundations of research and science.

if you dont take ideas for granted without reflecting on them and wondering why something is the way it is, always carefull to see the things that make your old theorie and ideas people taught you obsolete only then can you truly achieve something in those fields.
but you're true. its not your duty to state all the facts, theories and hypothesis here for me. but you shouldnt think of it as a bad thing that i state my questions and maybe make other people wonder too
#104 to #100 - thasmackdown **User deleted account** (10/05/2013) [-]
Ya, you are only going on one end of it, another end of science is
Ask a Question.
Do Background Research.
Construct a Hypothesis.
Test Your Hypothesis by Doing an Experiment.
Analyze Your Data and Draw a Conclusion.
Communicate Your Results.

You didn't ask an unbiased question as real science would have you do it.
Instead you divulged to me a cynical statement leading others to draw a conclusion, much like yellow journalism, you put your first thoughts first without using the other steps of the scientific method...

In reality what you said with your cynicism was communicate your results without doing any of the other steps.
#108 to #104 - kanedam ONLINE (10/05/2013) [-]
you're implying a lot into my words...   
   
i was simply replying to your words: "Take for example the fact that the bottom of your feet, that you walk on and grow calluses on, does not wrinkle " that a lot of skin on my body doesnt wrinkle... i neither said why, nor how, nor that you were wrong or i was right or anything... i just said that a lot of skin on my body doesnt wrinkle. period.   
   
i dont see whats cynical about it, it's the truth. simply put. maybe you interpret a lot into that... but it just simply is the truth. dont know why... just know that thats the way it is.   
   
and i'm not devoted to start research on such a topic, lol, with real labs and serious experiments.  i dont have to know the right answer or even search for it to point out mistakes in others explanations. i never said i knew the answer or who's right... you're the one spouting from the first comment in this thread your opinion. so why get furious over me just stating something obvious? (that not all of your skin wrinkles, and it's not just the calluses and the tough skin that doesnt wrinkle but soft areas too).   
   
so, just relax man... and have this pic so you understand how i feel about your reaction!

#110 to #108 - thasmackdown **User deleted account** (10/05/2013) [-]
1. Why would you say a statement like that for no reason? Is that really something you do? It had no comical value, and it simply raises skepticism as I said before.
2. An experiment does not require a lab, or even much technology at all
3. I sound like a broken record at this point, but what you said has implication that what I said was wrong, when in fact I was not wrong, what you said is not wrong either, but acts to question what I said, when in reality we are both right to an extent, just you do not explain that part.
#112 to #110 - kanedam ONLINE (10/05/2013) [-]
you neither explain my part nor your part... you stated something and i showed you the flaw in what you said. thats all. you never explained why yours was right, nor why mine was wrong.

i had a reason to state that. it was simply to point out something about the information or hypothesis you told is wrong. thats the whole purpose of it. no need to get offended. in my opinion its good if people are sceptic and search for answers, not simply believing something someone said without explaining questions that come with the hypothesis or facts that contradict it.

i mean, that topic really is almost useless, but still you go in and say something that i myself can not quite accept as the truth. so why would it be bad for me to point that out?
as you said, i plant the seed of doubt... and in my eyes thats a good thing. i'm not saying you're wrong, but i'm also not going to tell people that you're right. i'll point out the mistakes i see in an explanation, giving everybody a chance to explain why this contradictions happen. maybe they have a reason for it after all... but if not, then it's good to not take that persons hypothesis for granted.
#114 to #112 - thasmackdown **User deleted account** (10/05/2013) [-]
uhm, I did explain it, "take for example the fact that the bottom of your feet, that you walk on and grow calluses on, does not wrinkle"

I also want to stress the fact that I said "for example" and I was also answering someones
specific statement. the hard part at the bottom of your foot is a callus, babies haven't developed this yet because they haven't been walking on their feet.

Then you tossed in your statement.

#31 - minidino (10/04/2013) [-]
Or maybe it's because all our cells contain water containing a certain concentration of salts within it. Your cells allow water in through osmosis to try and even out those concentrations so that the outside matches the inside.
#62 to #31 - gardeivor (10/05/2013) [-]
Read the article in the top comment, it says that the fingers dont prune if the nerves in the fingers are damaged
User avatar #122 to #31 - pokemonstheshiz (10/05/2013) [-]
if that were true, it would produce a bloated effect, not a wrinkled one. If it was caused by osmosis, it would be close to an even distribution, seeing as that's the basic principle behind osmosis
#23 - anon (10/04/2013) [-]
Ok, then how come people don't prune in salt water? Misinformed post is misinformed.

The reason is different than the mechanism, the mechanism is Osmosis not the nervous system.
User avatar #123 to #34 - pokemonstheshiz (10/05/2013) [-]
If it were osmosis, wouldn't it be more likely to produce a bloated effect rather than wrinkles? The whole purpose of osmosis is even distribution, wrinkles are inherently uneven
#125 to #123 - bobbysnobby (10/05/2013) [-]
osmosis from low volume to high volume goes from fingers into the surrounding fluid.
User avatar #126 to #125 - pokemonstheshiz (10/05/2013) [-]
I understand what osmosis is. But the point is that if it were caused simply by osmosis it would be evenly distributed among the cells in your fingers, and they would be slightly larger, not wrinkled.
#128 to #126 - bobbysnobby (10/05/2013) [-]
It is caused by osmosis I dont know what to tell you. Its like saying my computer is powered by electricity and someone says no its powered on by hitting the power button. No the thing that powers it is the electricity.

The operation is basically 2 processes one physiological one chemical, but volume of the fingers is decreased not increased.
User avatar #129 to #128 - pokemonstheshiz (10/05/2013) [-]
Osmosis goes from high gradient to low, your fingers do not have a higher gradient than water. Not to mention your skin cells have selectively permeable membranes, they don't let everything in or out.

Actually, there were some researches done that actually prove that wrinkled fingers actually weakens your grip since there is less surface area.
#142 to #51 - greenbracelet (10/05/2013) [-]
wrinkled = MORE surface area = more grip.

get it together man.

**collegedood rolled a random image posted in comment #9 at Just how big are the ponies? **   
im not trying to dispute the research (i know nothing about it), but take a pliers  and how it is rigged at the end, isn't that to hold material better since it would slide if it was a flat surface? same with the fingers, fingers become slippery when constant water is on them, but wouldn't it be easier to grip something with larger grooves like pruned fingers?

Well it actually HAPPENS by the almost membrane-like water protective layer getting rubbed off. This is why if you're scrubbing your hands they wrinkle faster.

that's because it is.

same with your eyes, your eyes increase or decrease in water with less or more salt in it, which it happens to hurt so god damn much in either sterile or salt water. also some pools put 1%-ish salt in it, in order to remove the whole hurting eyes thing

This actually gives credence to the recent theory that humans evolved as semi-aquatic mammals, having to endure most of their lives partially submerged in water. It's called the aquatic ape hypothesis.
Other characteristics that support this:
-Humans are mostly hairless. Think of dolphins, whales, hippos, porpoises. It reduces drag. Our heads have hair because they would logically be out of the water most of the time, and we would need sun protection.
-Bipedal. Apes have been observed to wade through water on two feet. Evolving balance on two feet would be advantageous in wet environments.
-Speaking. We have proficient speech abilities because of our ability to hold our breath when underwater.
-Facial expressions. We use our facial muscles to communicate a variety of expressions because that's what our ancestors were always focusing on.
-Picture related

Look it up, there are a lot more. This is what will be taught to future generations in grade school in my opinion.
