the dragons and wyverns thing makes me so unreasonably mad i’m sorry

actual biology: whales are fish because they evolved from mammals which evolved from reptiles which evolved from fish. everything is much more complicated than the simple boxes our brains like. what classifies a species is somewhat arbitrary human concept

losers: that’s a wyvern because it has 2 legs and 2 wings, dragon is incorrect >:(

#i’m aware this is so dumb and doesn’t matter but #dragon #evolution #biology

Scientists are amazed at the discovery of a bristle worm with such sharp-seeing eyes that they can measure up to those of mammals and octopuses. Researchers from the University of Copenhagen and Lund University suspect that these marine worms may have a secretive language, which uses UV light only seen by their own species. The advanced vision of such a primitive creature helps to settle an epic debate about the evolution of eyes. The Vanadis bristle worm has eyes as big as millstones—relatively speaking. Indeed, if our eyes were proportionally as big as the ones of this Mediterranean marine worm, we would need a big, sturdy wheelbarrow and brawny arms to lug around the extra 100kg.

[image id: a four-page comic. it is titled "immortality” after the poem by clare harner (more popularly known as “do not stand at my grave and weep”). the first page shows paleontologists digging up fossils at a dig. it reads, “do not stand at my grave and weep. i am not there. i do not sleep.” page two features several prehistoric creatures living in the wild. not featured but notable, each have modern descendants: horses, cetaceans, horsetail plants, and crocodilians. it reads, “i am a thousand winds that blow. i am the diamond glints on snow. i am the sunlight on ripened grain. i am the gentle autumn rain.” the third page shows archaeopteryx in the treetops and the skies, then a modern museum-goer reading the placard on a fossil display. it reads, “when you awaken in the morning’s hush, i am the swift uplifting rush, of quiet birds in circled flight. i am the soft stars that shine at night. do not stand at my grave and cry.” the fourth page shows a chicken in a field. it reads, “i am not there. i did not die” / end id]

a comic i made in about 15 hours for my school’s comic anthology. the theme was “evolution”

#dinosaur #evolution #comic #prehistoric #animal #wildlife #paleontology #biology #poetry #comics #original #my art #archaeopteryx has no direct living descendants i know #but i wanted something aerial and the dinosaur to bird connection is classic and well known anyway #also the chicken over any other bird is very on purpose #its the mix of truth and comedy and genuineness and the fantastic in the mundane #its me asking you to see something so wonderful in something taken so un-seriously #and to love it both ways #also the jurassic park thing #where someone saw the reconstructed gait of a dino #and said. hey hang on. i know that walk. #and pulled up footage of a chicken walking #which jumpstarted the entire study into the link between dinosaurs and birds #in the end take whatever you want from it i just thought id provide some insight #i always like it when other artists do #the point is that i enjoy when people laugh at the end and when they dont #and i like it when they cry. i like it best when they both laugh and cry. eeaao intent #anyway mourn your losses but to live is to change #also hi guys i finally figured out tipping after 5 months so no more annoying ko-fi link

If you've seen trivia posts going around, may have seen ones about the baculum, a bone in the penis whose purpose is to help support erections which is present in most placental mammals, including non-human apes, but which is conspicuously absent in humans.

Those posts typically don't go into why this is the case, which is fair enough, since the question is far from settled. However, there are a lot of hypotheses about it, and some of them are pretty fucking wild.

I think my personal favourite is the recently proposed idea that, since soft tissue injuries tend to heal more rapidly and completely than broken bones, a flexible and resilient boneless penis constitutes a reproductive advantage in situations where genital trauma is common, possibly as a result of the development of upright posture rendering the penis more prone to blunt encounters.

Like, imagine humanity's proto-hominid ancestors going "actually, bipedalism is great" and promptly getting whacked in the ding so much that it exerted evolutionary pressure on the morphology of the penis.

List of Extremely Cursed Knowledge

Having autism and ADHD is a blessing and a curse because on one hand, I’m basically a walking encyclopedia of random facts and information. On the other hand, a fair amount of that information is so fucked up that it’s not socially acceptable to share it with anyone. So naturally, I took every fucked up fact, every bit of twisted trivia, every bit of cursed knowledge that I could come up with off the top of my head and compiled it into one big list to post on the internet. Some of this information may permanently ruin your (you, the reader) perception of certain things. None of this information should have ever seen the light of day, and a fair amount of it was never, ever meant to be known by humans.

You cannot unlearn anything on this list. This is your chance to scroll past.

You have been warned.

According to FDA standards, a jar of peanut butter is allowed to have up to seven (7) rat hairs before it’s considered unfit for human consumption. If it has 7 or less rat hairs it will still be sold in stores.

If I just ruined peanut butter for you, don’t google the FDA regulations on any other foods you enjoy.

Human teeth have 36 calories each.

The average human body has roughly 125,000 calories. This is actually relatively low, which makes cannibalism in humans generally unsustainable.

Human meat tastes like pork.

Penguins have been observed practicing necrophilia.

Dolphin vaginas secrete a substance that acts like an aphrodisiac on steroids. When scientists swabbed some of it on a chimpanzee’s penis, it masturbated so furiously that it had a heart attack and died.

Dolphins have been known to intentionally commit suicide if kept in poor conditions.

Scientists that work with cockroaches often become allergic due to exposure. Simultaneously, they also develop an allergy to chocolate and pre-ground coffee. Make of that what you will.

Dolphins have been observed masturbating using decapitated fish heads.

Dolphins have been observed getting high on pufferfish venom recreationally, sometimes even passing a pufferfish around like a joint.

There’s a LOT of rape across the entire animal kingdom. Like, a LOT. It’s especially prevalent in dolphins, otters, ducks, penguins, and primates, to name a few.

On a related note, female ducks have corkscrew shaped vaginas. Male ducks also have corkscrew shaped penises that measure in at a whopping eighteen inches.

The barnacle has the largest penis to body size ratio in the animal kingdom, with its penis being up to eight times as long as its body.

Chimpanzees have been observed using frogs as a fleshlight.

A disembodied human head weighs about 10-12 lbs and is balanced in such a way that requires you to use both hands to pick up.

Pigs will eat every single part of a corpse - including bones. In 2012 a farmer in Oregon was eaten by his pigs after having a heart attack and falling in their enclosure. This also makes pig pens a prime spot for dumping bodies.

A body will decompose faster if you fill the rectal cavity with yogurt before burying it

When burying a body, make sure to bury it in a heavily wooded area. If vegetation is too sparse and/or the body isn’t buried deep enough, it will be easily noticeable after a few months because plants will grow in much thicker directly above where the body was buried.

You cannot bury a body in sand, as sand is too porous. The smell will seep through and give away the location

The entire universe could theoretically exist as a false vacuum and collapse into nothingness at any moment without warning.

Any alien civilization advanced enough to detect life on earth is also probably advanced enough to destroy our entire planet almost immediately. At the peak of interstellar technology, the only limiting factor is the speed of light. If they decided to attack, we probably wouldn’t even know it was coming until the entire surface of the planet was already vaporized.

It takes three and a half rotations to fully detach a human head from its body.

Recently deceased bodies can experience rigor erectus, which translates to “death boner.” This is especially common in victims of hanging, as it’s primarily caused by trauma to the cerebellum or spinal cord.

There is an extremely real chance that you have unknowingly purchased a product that was made by modern day slaves at least once in your life. Coffee, cotton, fish, clothes, shoes, and technology are among the most vulnerable industries.

A decapitated head remains conscious for several seconds after separated from the body.

The entire koala population across Australia is currently undergoing a major chlamydia epidemic. It’s actually been extremely devastating for them and they’re currently facing the threat of extinction because of it.

Shellback Crabs: these crabs create their own shields out of clamshells; their semi-membranous bodies can be pressed into the contours of the shell, producing a suction mechanism that holds the shell in place

The members of this genus (Hypoconcha) have a series of unique adaptations that facilitate this kind of camouflage behavior. Many of the Dromiidae crabs (e.g. hermit crabs, sponge crabs, shellback crabs, etc.) are equipped with a specialized pair of legs that enables the crab to hold a shell, sea sponge, and/or ascidian against their body, but shellback crabs also have a flexible, semi-membranous body that can be tucked more firmly into the contours of a bivalve shell, producing a suction mechanism that keeps the shell firmly locked in place.

The body of the shellback crab is also covered in a very fine layer of hair-like structures called setae, and when the crab presses itself against the shell, these membranous "hairs" can take on an almost translucent appearance, particularly around the margins of the crab's body.

I recently posted some photos/info about some of the crabs in the genus Lamarckdromia (which belongs to the same family) and as I was doing the background research for that post, I was just kind of mesmerized by all of these weirdly adorable crabs that seem to exist within the Dromiidae family tree. Each genus has its own unique adaptations that allow the crabs to use specific materials for camouflage -- some of them use living sponges, clamshells, ascidians, etc.

And I could not stop laughing at the little faces on these crabs. They've all got the same bemused/indignant expression...as if some random asshole has just walked up to them, shoved them over, and announced to the entire ocean that there's a crab hiding beneath that disguise; as if that actually happens to them quite a lot, and they're getting really sick of it.

Deity who's unacquainted with concept of evolution creating a world with, like, twelve different kinds of creatures, thinking "yes, that's a good number – nice and symmetrical", then going on vacation for a couple million years and being very upset at what's waiting for them when they get back.

#concepts #theology #evolution #worldbuilding #they keep throwing extinction events at the world in an effort to get a clean slate and start over #life just keeps getting weirder in response #they're practically at their wits' end #and that's a lot of wits to be at the end of

Okay, so this is really cool! You have this phenomenon where some plants grow edible appendages to their seeds to entice ants to carry them underground where they can safely sprout. And then you have wasps which lay their eggs on the leaves, stems, and other parts of plants and trigger the growth of galls (swellings) which both feed and protect the wasp larvae until they reach maturity.

The boy who was watching the ants noticed they were taking wasp galls underground, too. Further exploration found that the wasp larvae were unharmed inside the galls; the only thing the ants had eaten were edible appendages similar to those on the seeds they collected. The wasp larvae stayed safe inside the ant nest, feeding on their galls, until it was time to emerge and head back out to the surface.

So it turns out that the edible portions of the galls have the same sorts of fatty acids as the edible parts of the seeds. And those fatty acids are also found in dead insects. Scientists think that the wasps evolved a way to make the galls they created mimic the edible portions of the seeds to get the ants to collect the galls. This isn't the only example of wasps making use of ants as caretakers for their young, but it's a really fascinating example thereof--especially if you consider ants evolved from wasps at least 100 million years ago.
