why do we have hair in your bum

Butt hair is not common in everyone, but it runs in some lineages. The human body was never wired for convenience. It might be some odd evolutionary addition that was never really removed, something that was once of benefit, but as we evolved, it became quite useless just like the appendix. The original function of butt hair is protection. You must never forget that every hole in your body-including your butthole are quite sensitive. So like every other sensitive hole in your body, there is a need to protect your butthole. At our current evolutionary position, we stand upward in a straight posture.


In this straight posture, the muscles for sitting convenience completely fold behind it, giving it all the protection it requires as long as we ensure it is clean. But before we acquired this posture, we would have ended up with a posture like that of the gorilla. Try to bend over when your pants are off your ass. You will discover that the both sides of gluteous maximus are no longer completely sealed. So imagine you are in that position at all times, everyday. If this were to be the case, you would have had your butthole exposed to open air, sun, and even parasites.


Having hairs in your asshole in such circumstances would make the hair a kind of insulator and sunblock and prevent the small critters you hate having around that little hole from making it their permanent residence.
Grooming our can be comparable to landscaping. We tweeze our eyebrows, trim our beards, and shave our legs to strip awayВ thousands of unwanted hairs. In the process, we come across an unsightly view в butt hair.


While weвre aware it exists around our anus, we wonder, "does it serve a purpose? " In Sci Show's, "Why Do We Have Butt Hair? "В host Hank Green explains no one actually knows why we have butt hair, but (no pun intended) it may simply exist because there's "no significant evolutionary pressure against it. " In other words, it does not get in the way of humans procreating. It may just be a side effect of unintelligent design. Other theories suggest facilitates scent communication. Throughout human evolution, communication through scent has played a pungent role.


This is why we have body hair in the same areas where we produce odors. The hair is there to hold onto sebaceous, or oily, secretions that have their own smell and are consumed by bacteria that produces even more smells. Since we all have different smell compounds, and our own microbiomes, each of us smells differently. It is presumed our early human ancestors used their to help them with everything from broadcasting territorial rights to attracting mates. Butt hair may simply be another way our ancestors enhanced their smell profiles.


Lastly, friction may explain the evolutionary purpose of butt hair. Skin rubbing on skin causes friction, which can lead to irritation, rashes, and even infection. Hairs may act as a bit of a protective layer, and those sebaceous secretions hair helps spread work to reduce the pain of chafing. Butt hair could act like a natural anti-chafing cream. It's important to remember there hasn't been much research done to verify these theories, and "not every bit of our physiology needs an evolutionary purpose. "
