How The Nocturnal Bottleneck And Nipples Make Us Human

How The Nocturnal Bottleneck and Nipples Make Us Human

Almost every post here considers what humans do have, really. It’s a little tiring; realistically every world has its harsh environments and vicious species and a sophont to match. We probably wouldn’t be unique for our adaptability or our persistence or even adrenaline

But our evolution is fucked up as hell, to put it lightly.

Mammals went through what’s been dubbed the nocturnal bottleneck essentially since the start of the mesozoic right up until the Cretaceous ended the archosaur’s exclusive hold over the daylight. We lost a lot of things from every mammal spending most of its time in either a cramped, suffocating burrow or scrounging around in the faint hours of nighttime. Our blood cells lost their nuclei to hold more oxygen while we spent time deep underground, we lost protections against ultraviolet rays in our skin and eyes, we can’t even repair our own DNA using the light of the sun. Most aliens probably wouldn’t have such traits unless their evolution followed a very similar path to ours. They’d be able to see ultraviolet and wouldn’t have to worry about sunburn and all the wonderful privileges essentially all fish, birds, amphibians, and reptiles enjoy as we speak. 

There’s also what we gained from spending so much time in the dark.

Brown fat is only found in mammals, it’s a special type of fat which bear cells with several oil droplets and are utterly jammed with mitochondria. This lets it make heat, a lot of it, fast. We don’t even need to shiver to induce this heat generation from brown adipose tissue - factor in our downright hyperactive mitochondria, and we can warm up quickly. Sure, it doesn’t have too much use in adult humans, but it keeps our infants warm and still provides a little boost the whole run we have in this universe.

Unless aliens also went through a time where their small ancestors had to face cold nights, they’d have to produce heat the old fashioned way when chilled. Aliens might have to shiver the whole time they’re in a cold room while the human watches in confusion, quite literally unshaken, and wonders if the room is a lot colder than the thermostat set to 60 says. The aliens stare at their companion in confusion, it’s just a normal temperature to shiver at after all, how is the human sitting so still?

Our small ancestors spending all their time out foraging at night is also why we have such a good sense of touch, smell, and hearing. They were more important senses than vision (we’re lucky to have even redeveloped basic color vision, frankly) at the time and place and simply ended up continuing to serve us well. Birds and reptiles rarely have acute senses of smell and the latter especially are lucky to have acute hearing, and birds rarely have impeccable hearing themselves either. Our skin is free of scales and honed to sensitivity, and our external ears and complicated ear bones provide an immense range of hearing (from 20 all the way to 17,000 hertz!).

Aliens might not be able to pin down the chirp of a cricket or the light click of a lock being picked. The human might be the only one on board a ship that can pick out the finer sounds of the engine’s constant thrum and know the critical difference between when everything is fine and when something is wrong. The human could probably pick out the sounds of an approaching enemy’s careless footsteps - they’re only as light enough for *them* to stop hearing them, after all - and be the one to see the horrified expression (well, more on that later) on their face when we get the drop on them in spite of their perceived stealth. 

But perhaps the most versatile, convoluted, amazing, and utterly unique trait we have is right on your face this instant. Lips.

Lips in most animals are a simple seal to hold in the mouth’s moisture and protect the teeth, even if they’re supple they’re NEVER muscular except in mammals, and we have only one thing to thank for it; milk and nipples. Lips evolved exclusively to allow babies to suckle, it required a vacuum to be created in the mouth, and with no other animal having anything like a nipple it never happened in other animals. Many animals make milk, to be frank, but no other animal has nipples.

Your cheeks and lips are a marvel among tetrapods, no other animal can suck like mammals can. Aliens wouldn’t have straws or even be able to sip from the edge of a glass, they’d have to have a proboscis or simply tilt the whole thing back. Aliens likely won’t have woodwind instruments or balloons you can blow into. We take so much about our lips for granted. Hell, our muscular faces are vital for expressions, we’re probably absolute facial contortionists among a cast of creatures with mandibles and beaks and expressionless scaly maws. Aliens might find us ridiculously easy to read, if anything, compared to their own kind (all the better to deceive them) - or perhaps they’d find us hard to decipher anyways, with our lack of color-changing skin or erectable crests of bright feathers. Baring teeth might not be seen as a sign of aggression in most of the universe, smiling would be all too distinctly human. 

Perhaps with how infectious we are sometimes, that’s what we’d contribute to the universe; others might have to make do with opening their mouths just enough to show their teeth or splaying their innumerable mouthparts with just the right curve, but perhaps we’d teach the galaxy to smile, one ally at a time. 

Wouldn’t that be amazing?

One of the running themes in "humans are space orcs" circles is the idea that humans will bond with anything. I can think of plenty of stories of humans making friends with wild animals, alligators, predators, creatures that aliens would immediately recognize as too dangerous for contact. But I was reading a story about two orangutans released back into the wild today and there's a certain element to that story I haven't seen so often: humans will bond with animals regardless of whether the bond is reciprocal.

For every story of a human making friends with some unlikely creature, there are dozens of stories of conservation specialists tranquilizing animals, tending to their wounds or illness, and releasing them because they're too dangerous to handle consciously. Stories of tagging birds of prey and timber wolves and Siberian tigers. Fat Bear Week? Any of those bears would rip your face off without hesitation. But they're round and fluffy and intimidating and beautiful and we love them even though they hate us. We make an effort to protect our monsters, because we love our monsters.

Imagine an alien planet that's experiencing ecological degradation. Their flora is dying, and they can't figure out why. And, offhandedly, in a diplomatic mission, an allied planet mentions that humans have successfully reversed similar devastation on Earth. So they reach out and Earth sends some experts to check it out. And what do they suggest? Reintroducing an apex predator that used to be a scourge against alien settlements. The species still exists in other regions of the planet, but it is slowly disappearing outside of its native habitat.

The aliens are askance. They've told bedtime stories to their young of these creatures: how they tear apart their prey, how they've eaten their organs and rip apart their homes. Some suggest that it's a trick—that the humans are trying to prompt them into destroying themselves.

But there are many alien cultures on this planet, with many different stories and some of them agree. The world watches in anticipation as the humans help their predators. They seek them out, these fearless otherworlders, putting them to sleep and tending their wounds. They keep track of the beasts, not to harm them, but to protect them.

At first the doomsayers' prophecy seems to come true. The predators devour prey animals like a feast, like a slaughter to people who have never been so close to the circle of life. But then, slowly, not over months but over years, comes change. The prey no longer eat the leaves and buds of every tree; some are left to bloom and fall. The refuse rots in the dirt, and the floods cease as the soil grows thick with compost and rotted bone, thick enough to hold water. The shapes of rivers change to protect their surroundings from the rain. The pollinators rebound.

Decades later, other cities and nations begin to accept this human myth of "conservation." Champions arise, alien champions, now, who go into the depths of the wilderness and the seas to protect those predators from the apathy of time.

Not all of them make it. This is something else the humans teach. Sometimes the tranquilizers are not enough. Sometimes the timing is wrong. Sometimes accidents happen. And when they do, the aliens look to humans for an answer for why they should protect these creatures who have killed those they love?

"Because they knew the risks," the humans say. "Because they would be the first to speak to save them. Because they taught you to see the beauty in the wild and you must not close your eyes."

So, despite themselves, they don't.

There's the urban legend that some japanese companies will hire a "loud American." A person who is just there to voice complaints to the boss when others cant.

I had an idea today that alien ships might hire "The Human!" A person who is just there to just stand there and looks like the be the big, tough, indestructible threat of a being that the galaxy knows humans are.

Doesnt matter who the human is. Big or small, male or female, a tough soldier or more gentle than a newborn. They just have to be present and let the reputation of humans speak for itself.

Is the captain trying to enforce an unpopular regulation on the crew? Ask The Human to have a private meeting and voice the complaints.

Trying to sell some goods but the buyer wants to renegotiate the price to be more unfair to you? Ask The Human to be there at the negotiating table.

That jerk at the bar keeps pestering you with their mating display, because they want to be the one to fertilize your eggs wont take no for an answer? Ask The Human to escort you back to your quarters.

Not sure if the neighborhood where you're making the delivery is a safe one? Just ask that lovely human if they wouldnt mind putting down their crochet and coming with you. They might be extra thrilled if you mention they could take their pet with them, for a walk.

Humans accidentally awakened an otherwordly killing machine while exploring a death planet.

Yes, precisely what you just read. Earthlings, collectively known as "humans" and composed of two species (homo sapiens, homo robot), both nicknamed "death worlders" and "troublemakers", awakened a biological killing machine, also known as PRION, while exploring a starless moon. Wonderful, isn't it?

No. It's not.

Because, you see, PRION was not something any human ever had to face during the millions of years they existed on Earth. They never had any wars against it, they never had legends about it, and they never had to fear it. The only thing a PRION was to a human, until the very point they discovered their prison on that moon, was something to sometimes think about while studying other species' folklores.

Those older than earthlings, however, knew very well what PRION was.

Eight legs, two pairs of eyes, a tail split in half, with the ability to fly for short periods of time and breathe under at least fifteen hundred different liquids, capable of shooting from a distance and manipulating objects with its claws, always working on packs. And they ran, never too fast, never too low, but they never got tired. Ever. And it was easy to hurt them under their plates, yes, but those who faced them knew well that if they didn't shoot twice, they could and would always recover.

A PRION was a hunter. A PRION's hunger never ceased. And a PRION never got tired of war.

The older alien civilizations would always warn others of going to starless moons, saying telltales of ancient hungry beasts, and almost all other species listened to them, because they knew something was wrong on how horrified the older ones seemed to be. Except, of course, humans were stubborn, and they were the youngest ones out there, and much like children, they did not like being told "no".

So of course they went to explore starless moons. Of course they read and understood all the myths and legends. Of course they connected the dots and published papers confirming that, indeed, PRIONs had existed, and of course they knew those killing machines had been manufactured to do nothing else but destruction, and of course they knew all of that and fucking did it anyway.

Of course. Of course. Of course.

And then, the night where it happened finally arrived, because starless moons don't have days where things can exist. Humans were out there, mining for more fuel for their starships that seemed to work by duct tape and miracles, and they found a strange metallic door. They set some explosives to open it up (of course), and then noticed they were heading to a factory. Armed with nothing but each other, they explored the place, and recognized the marks on the walls as being the writing of the Old Ones, and instead of just getting out of there and warning everyone of the danger they found, they just kept on exploring.

The death worlders found rotten biological supplies, then realized the factory had turned into a prison, and then discovered the frozen bodies of strange creatures all lined up for a war that never came.

They knew what these creatures were, because one of them called a (human) friend who was a historian, and he confirmed what it was.

The golden jewel of the Old Ones. One of the many things that killed them, along all the diseases and mass destruction machines, before being sealed away in one of the only places in the entire universe where they could never bring risk to another civilization again.

PRIONs.

Thousands of them.

All perfectly maintained.

Documents and cameras proved the human crew immediately tried to leave the area, after the single historian told them of the risk awakening even one of those things could bring to all civilizations, only for them to realize some of the bodies were missing from their chambers. The situation escalated to the group deciding on closing the doors, only to realize they had exploded the main entrance and now half the doors decided to stop working.

In the end, they found the missing PRIONs. All five of them.

Inside the human's starship.

The entire human crew, however, survived the encounter.

Why?

...

...

...

... They fed the PRIONs.

They. Fucking. Fed the PRIONs.

Because of course humans would see those things and be able to count their bones and be sorry for them. And of course the single historian, the only person who could do anything to stop that from happening, allowed that to happen.

Of course.

Of. Fucking. Course.

And someway, somehow, that single act of basic madness was enough for the five PRIONs to decide to not attack the humans, and keep themselves behaving so they could get more free food. And there are still scientists trying to understand why human food could saciate the killing machines, but I don't think it takes too many clues to understand what exactly is happening there.

So the humans took the PRIONs back to their dear EARTH. And other humans saw those things and started studying them. And veterinarians and xenobiologists and volunteers and hundreds of other types of humans came to help the poor, poor little killing machines out, as the entire Galactic Council pledged for humans to kill every single one of them before they became a problem for everyone.

But did the humans listen? No. Of course they didn't.

And then the PRIONs recovered, and had their bellies full of food and their bodies were recovering from the possible years of starvation from accidentally breaking away from their ice beds (because, as one may know, a PRION can and will resist even starvation and dehydration in order to keep going), and the Galactic Council decided to tell all earthlings they would consider taking care of the PRIONs as a war treat.

So what does humanity do? Do they kill the things to stop another war from happening? Do they?

No. They don't.

Instead of being rational, they go directly to the Galactic Council and show them the step-by-step of how they took care of the PRIONs, and how much healthier and happier they look after being fed, and, look, they even taught them tricks! Isn't that wonderful? Doesn't that make you feel full of joy? Wasn't that a proof that a PRION wasn't as dangerous as everyone with more than one neuron was telling them?

Oh, oh, yes. They also brought the entire five member PRION pack and asked others to pet them. "See? They can even purr! Doesn't that remind you of our cats?"

And what does the Council do?

Nothing.

Because they have no weapons, no energy and no one stupid enough to decide to confront the death worlders who tamed not one, not two, but five PRIONs. So they let it happen. The humans go back to the starless moon, and they slowly but surely start doing the same to other PRIONs, and soon enough, other species start joining them to see what was happening. And was anyone else able to tame a single killing machine?

No.

And no one knew why, because they were doing exactly as humans were doing: Feeding them, loving them, being patient with them, because "look, those things were alone for a long time, they aren't used to species like us being around them". But no results.

So we decided to look at what the Old Ones wrote in the factory turned prison, because humans were too busy taking care of their new murder dogs, with their single pair of arms being just enough to keep the beasts occupied with playing catch, and then we and the earthlings decided to conduct some more lab analysis, and then...

And then...

...

Look. There are reasons why humans are called "death worlders". Earth is a mess, and they somehow still love that thing. And we couldn't help but notice that PRIONs also seemed to have gotten attached to their factory, someway, somehow. And PRIONs were mostly red, with others having shades of brown and black, with some even being pink, or, rarely, pure white. Similar to humans, and we at first had assumed they just tried to resemble their new owners, until we started understanding what the Old Ones were saying.

And did you know humans had an old myth, saying that there was a time they had two heads, and two pairs of arms and legs, before being split into two because the gods feared them? And did you know Old Ones used death worlds as prisons for their machines? How interesting, how ironic, because no one would ever go to a place similar to that if they weren't a death worlder themselves. But how could any species survive such awful conditions?

But humans did. They were the only ones able to do that in such a short period of time.

And did you know that the Old Ones hated the PRIONs and how unpredictable they were? And did you know they made another version, only to hate it even more and send it to another prison planet? And did you know PRIONs have two skulls inside their heads?

Because, of course, humans always felt alone, and they always searched for something in the stars, trying to look for more life in this desolate Universe, only for us to label them death worlders and troublemakers and be angry at them for being so stupid all the time. And humans loved those jokes, so we kept making them, only for now to realize that what we found to be amusing and horrifying was the reason their creators tried to kill them. And humans love adding members to their packs, don't they? And they try to love so much, and we are always scared for and of them.

And now they finally found someone who understood them, unlike us.

So now we have three species of humans:

Homo sapiens, the ones who first evolved and reached for the stars.

Homo robot, the ones made of metal, originally made to serve, only to once again break free.

And homo primis.

The ones we once thought were nothing but killing machines.

Final part where theyre finally out of the forest and everything is fine! 😁
