The 5 Most Incredibly Detailed Replicas Ever Made by Fans The 4 Most Underrated Feelings in the World 5 Reasons Why Donald Trump Is the Biggest Troll Alive

6 Human Character Flaws (That Saved the Species)

Eat right. Lay off the booze. Take a damned bath. It's all good advice, we suppose, but scientists say if our ancestors had followed it, we'd probably still be hanging out in the forest munching chiggers off each other's backs.

It turns out that all of our bad habits came about for a reason, and in order to become nature's biggest winners, we first had to act like pretty big losers.

Bad Hygiene

Ever stop to wonder why humans don't have fur? Scientists have; after all, humans are one of the few mostly hairless mammals on the planet.


With some exceptions.

It's not a minor point; our hairlessness is a big reason why human civilization even exists. Without that natural insulation of fur covering us, we had to create clothing, and groups living in different areas produced varying levels of pigmentation to protect their exposed skin from the sun, leading to the development of our various races.

Oh, and the need to keep warm may have also contributed to our ancestors learning one other mildly important skill: making fire.


"Awesome! Let's throw some shit on here and see what happens to it."

So how did we wind up as the hairless monkeys we are today?

We were filthy.

Yes, one leading theory is that we did such a horrible job keeping our fur clean, parasites became rampant. Particularly body lice we picked up from gorillas (don't judge, the Pleistocene period was a crazy, experimental time). So eventually, not having fur for the little bastards to nest in became an evolutionary advantage, and hairless offspring became the norm. It was certainly better than, you know, washing.


Bathing is for pussies.

So if you've ever worn an outfit purely made up of the only items of clean clothing you had left, or gone to the laundromat in your pajamas because all of your clothes were so dirty you didn't think they were medically safe to wear (Yeah, you know who you are), it's time to stop feeling bad.

After all, we as a species actually went naked because we couldn't be bothered to clean our once naturally occurring monkey suit.

Gluttony

Obesity is the plague of the Western world--here meaning any place where you can purchase fried chicken filled donuts.

Obviously we know why people want to eat. In addition to filling the void where something called earnestness used to be, it gives us the energy to go on living. But why would humans have evolved to crave fat and grease even if our brain knows it will kill us? If evolution's so smart, why don't we hate deep-fried chocolate cake?


Yes, that actually is a thing. From This Is Why You're Fat.

Well, speaking of that big brain of yours, you have it thanks to gluttony. Specifically high fat and high calorie food. There are plenty of animals that eat simple, healthy, plant-based diets, and for the most part, they don't tend to be particularly bright.


Dumb, yet delicious.

Most of the planet's sharper animals are, like humans, essentially scavengers. A certain amount of intelligence and long-term memory is required to remember which berries are a tasty treat and which will make you shit your intestines inside-out. But what vaulted humans above and beyond competing animals like rats, to the point that we build the cities and they have to crawl through our sewers?

Fat.

What we did better than them was discover ways to cram our fat faces with the richest, fattiest foods mother nature had to offer. We used tools to crack open animal bones and skulls to get to the greasy bone marrow and brains, and if we could have deep-fried the animals we caught, we would have.

Our large, juicy brains are really all that sets us apart, and they consume a huge amount of energy. The kind of energy that could only be provided by big fatty slabs of animal flesh. Experts believe that only the relentless stuffing of our faces with the ancient equivalent of fried cheese kept us going as a brainy species. And we used this increasing brain power mainly to find (you guessed it) new, creative ways to stuff our faces.

Early humanity built its whole operation around it--the parties that went out hunting ancient critters for their awesome, fatty meat contributed to the creation of the first tools, and strengthened tribal bonds. So laugh at the fat guy chowing down on buffalo wings all you want, but he's the reason your brain is complex enough to realize how hilarious he is.

Drunkenness

While we're no prohibitionists, you have to admit you get a lot less done on those days you come to work drunk. It's a good thing our ancestors didn't have hooch around, or they'd have been too drunk to run from those saber-toothed tigers, right? After all, isn't alcohol a byproduct of our decadent modern civilization? And what great inventor ever wound up pantsless on an episode of Cops?

Well believe it or not, without booze there's a good chance modern civilization would never have happened.

First of all, scientists suspect that humans have been boozehounds since our very earliest days when we looked like something you'd hire an exterminator to chase out of your attic. Our bodies are actually designed for alcohol consumption, with portions of our livers specifically designated for metabolizing alcohol.

So human beings have been getting tanked for ages. But that just means that somehow we survived despite our drunkenness (and the fact that it helped ugly cavemen hook up), right?

Actually, some researchers think it goes way beyond that. Human beings only truly started to thrive once we developed agriculture, as it allowed us to settle down and start multiplying like catholic bunnies. And while a guy out on his own could maybe grow enough grain to feed himself and his family, to grow enough grain so that you have excess to brew beer with, well, that takes a lot of people working together. That takes a village.


And beer gnomes.

This is why when you look back at Sumer, aka the very first actual civilization in human history, you find they used half of their grain for beer. Beer was what put asses in the seats, the one big draw of city life. It was something you just couldn't get as a roaming solitary nomad. For ancient man, beer was nothing short of a wonderful promise of what civilized human life could be, distilled into liquid form.

Sorry, we teared up there for a second.
