The human body is an evolutionary marvel. It hosts the most intelligent brain on this planet (our brains can even hold up to five times more information the Encyclopedia Britannica…yikes), our bones are pound-for-pound stronger than some steels, and we are the best long-distance runners out of any animal.
But for being such an extraordinary living being the human possess a body that hosts an incredible amount of things that make no sense. For example, what’s the deal with male nipples? They serve no purpose, their comically unsightly, and can be sensitively painful (titty twisters anyone?).
And let’s not even talk about the human appendix. This roughly 10 cm long vestigial structure literally does nothing but cause pain. And who in their right mind likes pain?
What gives evolution?!?! So on this list, we are going to go over 25 things about the human body that makes no sense…none whatsoever. It’s almost as if evolution took a night off resulting in some epic evolutionary fails…and we’re the result. THANK’S EVOLUTION!

Our inability to biosynthesize Vitamin C
According to an article in a 2010 issue of Nature Education, humans and other primates as well as bats and guinea pigs don’t have the ability to produce vitamin C by biosynthesizing it from glucose (other animals can).
The lack of vitamin C bionsynthesis is due to mutations in the L-gulono-γ-lactone oxidase (GLO) gene which is responsible for coding for the enzyme that catalyzes the last step of vitamin C biosynthesis. However, in 2008, scientists were able to successfully re-instate the ability to produce vitamin C in mice. It might not be long before humans are next.
Proximity of our genitals to our rectum
This is not just aesthetically and anatomically awkward, but also unhygienic. Combined with our short urethras this leads to frequent urinary tract and bladder infections.
Prostate only causes problems in males
The prostate is a ridiculous organ in reality, with a minimally important function (secretion of prostatic fluid increases survival of sperm by a fraction) and a high propensity for developing cancer—most doctors will assure you they would get rid of it altogether at the first possible opportunity.
The prostate really contributes nothing to our survival and reproductive efficacy, and most (if not all) men would be happy with one percent less sperm in exchange for not having to spend fifteen minutes in agony every time they have to pee during the last thirty or forty years of their lives.
Our multifunctional genitals
It’s no secret that our genitals are destined to perform multiple functions and this can be pretty unhygienic. For example, when it comes to women, sexual intercourse pushes bacteria farther into the urethra, leading to UTIs. Additionally, both men and women can contract UTIs from two sexually transmitted bacteria, chlamydia and mycoplasma. And of course, it is from the vagina that babies are brought into the world.
Our inefficient sinuses
Humans have several sinuses—air-filled cavities that help with mucus and fluid drainage. But our maxillary sinuses, located on our cheekbone, drain upward. This often leads to the buildup of fluid and mucus, which can cause an infection.
