"people show their true colours in life threatening situations" no, they show you what they act like when they're mortally terrified, an emotion notorious for literally turning your entire brain off to the point where people who go into those situations as a profession need to be literally trained on how to not have that happen

shoutout to my favourite doctor who blooper ever

Doctor: Martha, you trust me don't you?

Martha: Of course I do.

Doctor: Because it all depends on you.

Martha: What does? What am I supposed to do?

David Tennant, breaking character and returning to his natural Scottish accent: Well there's a watch, but I've lost it.

"when i was your age, i was working three jobs to help support my family" and "when i was in college i was sleeping on a mattress on the floor and living off of soup"

YOU SHOULDN'T HAVE HAD TO DO THAT. NO ONE SHOULD HAVE TO DO THAT. I DON'T KNOW HOW TO EXPLAIN TO YOU THAT THIS ISN'T A CHARACTER-BUILDING LESSON, IT'S JUST BAD

zany to me how these um actually nihilists like to pretend that "um actually love/friendship/cooperation/kindness isn't real bc we evolved that way to benefit ourselves as a species..." um YES? that's also where tool use comes from? that's where cooking comes from? am i supposed to think social bonds & tool use & cooking aren't "real" because they evolved over time instead of appearing fully formed from the ether?

sorry u can't enjoy things. im a superior being twirling a fork in my bowl of delicious noodles whilst staring in adoration at the world

2,300-Year-Old Plush Bird from the Altai Mountains of Siberia, c.400-300 BCE: this figure was crafted with a felt body and reindeer-fur stuffing, all of which remains intact

This plush bird was sealed within the frozen barrows of Pazyryk, Siberia, for more than two millennia, where a unique microclimate enabled it to be preserved. The permafrost ice lense formation that runs below the barrows provided an insulating layer, preventing the soil from heating during the summer and allowing it to quickly freeze during the winter; these conditions produced a separate microclimate within the stone walls of the barrows themselves, thereby aiding in the preservation of the artifacts inside.

This is just one of the many well-preserved artifacts that have been found at Pazyryk. These artifacts are attributed to the Scythian/Altaic cultures.

Currently housed at the Hermitage Museum.

Bioluminescence Oil, 18 x 24 in, 2015, First in the Bioluminescence series. The light of life and the natural world. In all the vastness of space, as of yet, we know of only one planet that supports life. At least within some great distance from here, life is rare. Each organism being the exquisite and detailed product of billions of years of evolution, life is precious. This point of light and inspiration stands in contrast to the lanterns and lights that are historically thought to be sources of illumination but are now dimmed; mythologies and superstitions humans have created as we struggled in the dark of ignorance to understand our world. But the process of science has revealed a luminous, living planet, more amazing than we could have ever imagined. Where the intricacies of biology are miracles of evolution and our consciousness is a gift of natural processes that allow us to experience what it is to be alive.

Hot take

Night furies are actually perfectly evolved for hunting and killing other dragons and the only reason they aren't a dragon-hunting species like the death song or deathgrippers are is because DreamWorks couldn't have their adorable main character dragon be a "cannibal"

(below I'm gonna try to summarize what we've figured out in a convo with friends on discord)

(also tw animal death via predator)

First of all yes I'm aware that pretty much every decision made about their design was with consideration of the effect it would make on human audiences but hear me out

Night furies are most iconically known as dive-bombers. They are built for speed, high maneuverability, night-time camouflage and for striking targets from above. If we remove human settlements out of the equation (which would not have existed long enough to actually influence night fury evolution, come on), what does that leave us with?

They aren't built for catching fish for sure, they aren't very hydrodynamic and their head is round, wide, and their teeth are dull. Honestly, the monstrous nightmare is much better suited for catching fish, with its long neck, almost pelican-like jaw and rhamphorhynchus teeth

Compare to

Yeah the jaws look kinda like a porpoise of some sort but for that the whole body would have to be a lot more aquatic imo. The light fury looks a lot closer to an aquatic diver, it has a sleeker body, rounded fins instead of spikes, and a long neck.

I don't really see them hunting land animals either, they just don't look like they're adapted for that minus the resemblance with large felines and even then, they're too large to effectively hunt in forests.

The one thing I can kinda imagine them hunting is large mainland megafauna, but we're working with a setting that takes place pretty much exclusively on islands. And overall, dragons are the only abundant species there with the exception of fish and human-bred sheep and chickens.

In general, night furies have duller teeth, smaller claws and are smaller than most dragons. Disregarding the movies making Toothless weirdly OP, a night fury would be disadvantaged against most dragons in a 1v1 fight and besides, it has four huge weak spots that would highly discourage it from a direct physical fight - the primary and secondary tail fins. One unlucky rip in the membrane and the night fury is fucked.

The night fury however noticeably resembles falcons, given their dive-bombing ability and high maneuverability.

Falcons too have smaller beaks and weaker claws compared to most birds of prey, and for that they compensate by simply picking up speed, balling up their talons and Punching. Really. Hard.

And they use that ability to kill other birds, even much larger ones, by knocking them right from the sky.

Here, the night fury's plasma blast works the same way as a falcon's punch. Dragons are fire-resistant, so what the plasma blast does is really just a densely packed bolt of energy that has the effect of either stunning or outright killing prey by damaging its spine. And what the plasma bolt doesn't do, rapid contact with the ground would finish. And if even that doesn't do it, the night fury's wide jaws and dull teeth are just fine for simply clamping around the unlucky dragon's neck and strangling it, like a lion or a pitbull.

The night-time camouflage allows the night fury to soar for extended periods of time perfectly unnoticed in the night sky, and by the time it strikes, the dragon wouldn't even know what's coming.

Unless

Say the hunting night fury is aware of other dragons sleeping under the trees, as most dragons probably would at night (village raids aside, most dragons seem to be diurnal), so how does the night fury get them in position where it can use its signature attack? Well, there's That Iconic Screech Of Death. Since in the movies it tends to appear not just during dive-bombings but also when charging up a blast, I imagine it's something the night fury is able to control to some degree. So by simply fake-diving in close proximity to sleeping dragons, it can effectively terrify them into leaving their hideout and fly out into the open where it can easily take them out.

I dunno, the possibility of night furies as predators to other dragons just makes so much sense to me, I really don't know what other reasons there would be for them to evolve these particular adaptations.

And one more little headcanon to add to this whole rant - since night furies are significantly smaller and less equipped for dragon vs dragon fights and are primarily speed-based predators, I imagine there is this very likely scenario:

There is one dragon who resembles a hyena, a lil bit

Ok, rant over

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?

"don't make it political!" .... what proportion of death and suffering must occur before politics are involved. if this isn't political, what is even the point of any politics, ever. of democracy. the words are "by the people for the people." if i am going to be left alone by my elected representatives to "figure it out" - to undergo damage, hardship, fear. what the fuck did i elect them for. what was their job. the entire point is that they handle this shit. this is why we were supposed to be electing leaders.

poverty is political. misogyny is political. gun control is political. climate change is political. how much aid a community gets is political. what the fuck are you talking about. it's been political this whole fucking time.
