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!
The extremely narrow birth canal
Females have an unreasonably narrow birth canal, resulting in much pain and significantly increased risk to both mother and child during birth. This is a consequence of our quick evolutionary leap from quadrupeds to bipeds, resulting in our narrow pelvis.
Narrow Pelvis Also’s Responsible For…
As if childbirth wasn’t painful enough on its own, not helping the situation is the narrow width of the female pelvis, which, according to scientific estimations, hasn’t changed for 200,000 years, keeping our brains from growing larger.
Blood flows into each of your arms and legs via one main artery, which enters the limb on the front of the body, by the biceps or hip flexors. To supply blood to tissues at a limb’s back side, such as the triceps and hamstrings, the artery branches out, taking circuitous routes around bones and bundling itself with nerves.
This roundabout plumbing can make for some rather annoying glitches. At the elbow, for instance, an artery branch meets up with the ulnar nerve, which animates your little finger, just under the skin. That’s why your arm goes numb when the lower tip of your upper arm bone, called the humerus or funny bone, takes a sharp blow.
Males have nipples they don’t need
Nipples remind us that gender is anything but clear cut, especially in utero. Whatever your sex, everyone starts off as a female in the womb. One way or another billions of men around the world have nipples they won’t ever need for their whole lives.
The awkward wiring of the male urinary tract
The urinary tract in males passes through, rather than around, the prostate gland, which can swell and block urinary function.
