So how come that our asses evolved to the point that in case somebody does not wipe properly they are gonna wake up with smelly fingers? All this extra effort while most animals are just going on with their lives after taking a dump without any rashes or ichyness. What are the evolutionairy benefits for this behaviour if there is any ?
In: Biology
guess youve never seen a dog or cat lick their own bottom. most primates clean their bottoms.
a contributing factor is the modern diet and toilet. our ancestors had different diets which made “cleaning up” less of a need and squatting in a field had a much different position than sitting on the modern toilet
Our ability to stand upright requires dump truck ass checks. Which sadly gets in the way of our assholes.
our natural diet from thousands of years ago resulted in much less sloppy poo. There was no need to wipe each time. Just like wild horses in their natural habitat don’t need horseshoes.
There’s a couple different reasons for this. One, we stand upright and this requires larger and more substantial glute muscles to accommodate our bipedal structures. Two our diets are far different than they were when we first evolved to walk upright. The foods we eat now cause us to produce much sloppier bowel movements thus requiring extra cleaning to keep our backsides clean.
In addition to the other comments, consider something else – walking on two legs instead of four. Since humans walk upright, we need big, strong leg and hind muscles. In fact, the gluteus maximus (the butt) is the largest single muscle in the human body, and is much bigger in humans than our primate cousins. According to some sources, in fact, the human has one of the largest butt-to-body ratio in the animal kingdom. As you might imagine, having a longer, thinner channel that feces has to pass through causes more of it to get left behind.
TLDR – Humans have big butts, and it’s hard to squeeze through without leaving a mark.
What do you mean by “wake up with smelly fingers”?
Most animals dont have butt cheeks, their butthole is right there in the open, humans butthole is hidden between the butt cheeks, so the poo has to slide between the cheeks, compared to most animals where it just leaves instantly
You ever see a dog slide their ass on a rug? Guess what theyre doing lmfaoo
Lots of animals lick their asses after they poop. Have you ever had a dog?
Every living creature has an anus: Ants, horses, eagles . . . And us. While most creatures’ anuses do their jobs with little fuss, not so with human beings. The design of our anus is Providence’s little joke to keep us humble.
Consider, for example, the horse. We live across from a horse breeding establishment so I’ve had ample opportunity to observe these estimable animals in action. While they shit copiously they never get any on their hair (when was the last time you saw a horse’s behind fouled by its own waste?). The reason for this lies in the design of the horse anus. It is an extensible device that, when a BM is about to pass, protrudes a few critical inches, allowing the manure to drop straight to the ground without mussing a single hair. To further forfend fouling, there is no hair in the immediate vicinity of the horse’s anus, nor on the extensible process itself. What a remarkable design.
Not so with us. Our small orifice is buried deep in a meaty cleft, the margins of which have to be spread to their limit if there is to be any chance the thicket of long, nasty hair in the cleft will not be fouled by the passing of stool — a vain exercise in 99 cases out of 100. Moreover, while the horse can defaecate while standing, just let a human being try that! No we must squat. But not only squat, we must go through all sorts of contortions to minimize the amount of feces that will cling to the surrounding parts — which, as we all know, is another futile exercise.
To accommodate our flawed design, we are taught from birth to use wads of paper, magazine pages, dried corncobs and even stones, to wipe our filthy behinds. And this we must do! If we did not wipe, we would reek of dung from the cake of dingleberries between our cheeks and our pants, skirts, caftans and burkas, would be fouled with nicotine stains and clouds of flies would follow us down the street like goslings.
We are the most wretched of all creatures.
