HUGO HUGO OF YOU WE SING

YOURE SO GOOD AT EVERYTHING

[ambidexedition]

I miss forums but specifically, I miss how forums have specific areas for things. like if you weren't done reading a series yet but you wanted to talk about it, chances were there was a spoiler-free section specifically for the first book. if you just wanted to chat with people about whatever, there was an off-topic section. if you wanted to discourse about vriska, you went to the vriska quarantine threads. now I take one step into a fandom tag and am barraged on all sides by 20 different tangentially-related conversations and arguments that I care nothing about

[onemillionwordsofcrap]

Doylist explanation: They keep making new electric mouse pokemon because they're frantically trying to recreate the success of Pikachu. Or at least because it's tradition at this point.

Watsonian explanation: A major predator of rodents is birds of prey. A mouse that can deliver electric shocks to flying-types has a much higher chance of living to produce more offspring. Thus, convergent evolution fills this niche in every region. "Pikachu" is just the pokemon universe equivalent of "crab".

[bogleech]

Simple lifeform facts I take for granted that I've now seen blowing people's minds on here:

That sea urchins walk around and have mouths with teeth on their undersides

That corals are related to jellyfish

Barnacles being related to crabs and shrimp

Ants being an offshoot of wasps

Termites being totally unrelated to ants and all similarities just being convergent evolution (they're actually a group of cockroaches, but even science didn't know that part until a few years ago)

Starfish having an eye at the end of each arm

That the bodies of ticks and mites are also their heads, essentially big heads with legs (they even frequently have eyes way up on "the body")

Sperm whales have no upper teeth, and also their bodies are flat from the front

Goats also having no upper (front) teeth

Tapeworms having no mouth at all and just absorbing nutrients over their entire body surface

That flies are bigger pollinators than bees

That moths are bigger pollinators than bees

That wasps are just as important pollinators as bees (more important to many groups of plants) and when we say they're "less efficient" at it we just mean individually they get a little less pollen stuck to them.

That honeybees are nonnative to most of the world and not good for the local ecosystem, just good for human agriculture

That earthworms are also nonnative and destructive to more habitats than the reverse

There being no hard biological line between slugs and snails; all slugs aren't necessarily related to each other and there are gastropod groups where some have shells and some don't

That ALL octopuses (not just the blue ring) have a venomous bite

Most jellyfish and sea anemones being predators that eat fish

"Krill" being shrimp up to a few inches long and not some kind of microbe

Blue whales therefore being the deadliest predators to ever evolve as they eat up to several million individual animals per day

That krill are still "plankton" because plankton refers to whatever animals, algae and other organisms are carried around by the sea's currents, not to any particular group of life or a size category

Fungi being no more related to plants than we are, and in fact more like a sibling to the animal kingdom if anything

Venus fly traps being native to only one small area of North America in all the world

Parasites being essential to all ecosystems

Leeches not having a circular ring of teeth anywhere

That algae is not a type of plant

That most seaweed is just very big algae

That enough wood ends up in the ocean that plenty of sea life evolved to eat only wood

Speaking of which the fact that the "ship worms" that make tunnels in wood are just long noodly clams

Butterflies technically just being a small weird group of moths we gave a different name to

That insects only get wings once they reach maximum size and therefore there can never be a younger smaller bee or fly that's not a larva

Spiders not being any more likely to kill their own mates/young than just a cat or dog might, for most species maybe a lot less often?

Fun New Treasure Table. Roll A D10!

Normal boring treasure. What a disappointment.

Just a big vat of EXP. Grab a straw, lads!

Hot indie video games, but it's the D&D world so no-one can play them.

Colony of mimics playing the long con. They act like gold until you pay for something with them, then they eat the shopkeeper. Play along and they'll share the tastier organs ;)

Crabs. The Dragon heard that they're the end point of evolution so collected them all to become the ultimate lifeform.

Holy texts all written about the GM, which the GM reads to you in excruciating detail.

All the rejected Deck Of Many Thing cards that were thrown out for being too game-breaking.

Blades In The Dark characters who are in this system as part of their latest heist. Make a fortune roll!

Massive amounts of exotic physics matter. If you take it out, it'll start a chain reaction that will destroy the world. Also, in a neat physics discovery, it looks exactly like precious stones.

Me. Please let me out. It's been years.

15. gulper eel. ???

[elbiotipo]

Other posts go into more detail on this, but if you ever find a meme-like claim that a certain taxon has "never evolved" since so and so millions of years, it's most likely that, just a meme.

Crocodiles? Land crocodiles were, at many points of history, as common as amphibious crocodiles. In South America when it was a island-continent, they were among the main predators.

Horseshoe crabs? They have a rather well documented evolutionary history.

Sharks? Buddy you aren't even ready to know how fucking weird prehistoric sharks were:

(in order: Helicoprion (ONE reconstruction, we still don't have any idea how it worked), Stethacanthus, Aquilolamna)

Yes, for sure, some life forms have been very successful, I won't pretend the amphibious crocodile body plan hasn't been very succesful and conservative since the mesozoic. Plants are also remarkably conservative (not as much as you'd think, though). But every time you see the "X hasn't changed at all for millions of years, it's the perfect creature!" it's just a meme that obscures real life evolution and diversity.

Gently hands you these so w can watch together.

HORSESHOE CRAB BOIS!

I love these guys. It's so crazy you can just walk out on a random beach and see a bunch of heckin' 480 million year old living fossil dudes just sitting there, minding their own business. It's bonkers. Physiological evolution is for chumps. (also they unlocked a rare unique blood perk so that's cool).

It's also a case of the English word for something being very underwhelming. 'Horseshoe crab', really? This thing that doesn't even look like a crab and is one of the very few things left on this earth that is not (yet) carcinized? That only in the most abstract way possible actually resembles a horseshoe? All the alternate names for them are also just "thing crab".

I dunno, they're just so weird and unique that it just seems wrong to name them after other things. I would like to call them Blomblers™ instead.

[baroueman]

Star feathers are unique, they have high resemblance to pre-historic aquatic fauna; plants. Just like horseshoe crabs, their existence as a subset of species dates back to millenniums.

These are mobile versions of crinoids, that's a member of animalia (animal organisms), their original predecessors that came first --- the prehistoric plant-versions of crinoids that were rooted in the sea's sand as shown in the bottom figure were also animalia, but have differences in mobility. The rooted plant crinoids are among the oldest prehistoric members of lifeforms that dates back to even before the Cambrian explosion period. Fossils of crinoids are often seen in fossil marketplaces, alongside fake's, but these more recent versions of crinoids which have genetically adapted through evolution to thrive and live outside of the sand and actually swim amongst other fish, it was a characteristic often seen in the ocean's habitat.

[doomed-jester]

Every day I want to grab people and shake them and tell them to shut the fuck up about carcinization. Every day I want to tell them that crustaceans evolving into similar body types isn't that impressive and that it's just adaptation to their ecological niche. The way we define crab is so loose and these are species that are already relatively closely related anyway. Convergent evolution is a broad phenomenon and it happens all the time and there are way weirder examples than a thing that was already nearly a crab becoming a crab.

There's a horse that's a gorilla.

This is a real animal that existed and lived and walked around in a semi upright posture and it's related to modern horses.

Fish, reptiles and mammals all keep turning into sharks.

These animals couldn't be much more distantly related while still having a spine. Shut the FUCK UP about carcinization.

Anyway that's what I would say if I was on a website where people weren't all slightly obsessed with crabs.

Happy New Year!

Let's imagine it was the Earth itself that was going into its 2024th year. That is to say, we're compressing the entire history of the Earth into just the past 2023 years. What events would have happened when?

Well, not too much is certain about the first couple decades after our planet formed, until around 50 CE when we were hit by another proto-planet, Theia, and the debris formed the Moon. After a couple years of the planet cooling down again, the oceans formed out of boiling rain. The timing of the origin of life is very uncertain, but there are chemical signs it may very well have happened as early as the second century. Around 200 CE, the gas giants did a big funky orbit-swapping dance, and in the process inflicted the Late Heavy Bombardment on the rest of the solar system, meaning the Earth was suffering a ton of meteorite strikes for the entire third century.

The first indisputable evidence of life is from around 330, and the first stromatolites appear around 470. Those are basically the first fossils, stones created by layer upon layer of oxygen-producing cyanobacteria living and dying on top of one another. But even with oxygen producers evolving, it would take many centuries before oxygen became a major part of the atmosphere: not until the Great Oxygenation Event, which happened during the ninth and tenth centuries. That's also about the time the first complex, eukaryotic cells evolved through a symbiosis between an anaerobic archaean and an oxygen-breathing bacterium. The bacterium became more and more focused on just the oxygen-breathing task inside the larger cell, until its descendants were mitochondria, which as you all know are the powerhouse of the cell. The next seven centuries passed by with only slow, gradual changes, and life continuing to be unicellular and difficult to find in the fossil record.

(1735's Snowball Earth, by me)

From 1704 to 1730, the entire planet froze over. After merely two years of thaw, it happened again, this time lasting from 1732 to 1742. But these snowball Earth episodes set the stage for the evolution of animals that began right after. Across the mid-18th century, the bizarre Ediacaran biota, with its strange symmetries, fronds, and fractal-like pattern filled the oceans. In the early 1780s they went extinct, possibly due to a temporary drop in oxygen-levels, only to be replaced by a great variety of quite different creatures in the Cambrian Explosion.

(Class of 1799, by me)

Starting in 1784 and running for a few decades, the Cambrian period saw the origin of most of the modern animal phyla, reaching its most famous form in the Burgess Shale fauna of 1799. During this time, most animals still lived on the sea floor, either attached or crawling, with relatively few actually swimming creatures. Plants started tentatively moving onto land around 1817, and in 1825, the rising of the great Appalachian mountains caused a severe drop in global CO2 and thus temperatures, leading to the Late Ordovician mass extinction.

(Horseshoe crabs and sea scorpions on a beach in 1834, by me)

Bony fish first showed up during the 1830s, and around the same time plants were getting serious about inhabiting the land, evolving roots and vascular tissues so they could properly grow there. Millipedes and the ancestors of spiders were the first animals to follow them onto land. Our own fishy ancestors did not take their first step until 1857, by which point the arthropods were well established there and the plants had figured out how to become trees. The Late Devonian extinction, partially caused by the evolution of said trees and partially by the south pole freezing, played out in two pulses over the late 1850s and early 1860s.

(Swamp prominently featuring Meganeura and Mazothairos in 1889, by me)

Arthropods and vertebrates continued to gain adaptations to life on land. The insects became the first creatures ever to fly in 1878, and the high-oxygen atmosphere of the time would be especially good to them. Around 1884, a group of vertebrates called the amniotes, after the membrane that kept water inside their eggs so they could lay them on land without them drying out, split into two groups: the reptiles and the synapsids (which we mammals descend from). The next few decades would see the synapsids in particular being extremely successful as the supercontinent Pangaea formed. Until 1912, when a massive episode of volcanism caused the worst mass extinction of all time, the Great Dying, scouring the Earth of a huge portion of its life.

(A 1930 scene featuring the three branches of archosaur: dinosaur, pterosaur, and pseudosuchian, by me)

The 1910s were a period of slow recovery during which strange new forms of animal evolved. Many different, unrelated reptiles, such as the ichtyosaurs and plesiosaurs, went to sea, where they would continue to provide some of the most impressive creatures for most of the 20th century. On land, the dinosaurs first appeared in 1920, though for the next decade or so they'd live in the shadow of their pseudosuchian (crocodile-line) cousins. In 1934, Pangaea began to break up, resulting in another terrible pulse of volcanism that caused a lot of extinctions and left particularly the feathered and furry survivors with a lot of empty niches to fill, allowing the dinosaurs and mammals to diversify greatly. The last common ancestor of all modern mammals lived in the early 1940s, and by 1957 the dinosaurs had figured out flight, with Archaeopteryx usually being considered the first bird. Other dinosaurs took on an incredible variety of sizes, shapes, and forms. Some of the most famous ones include Dilophosaurus (1942), Diplodocus and Stegosaurus (1955), Iguanodon (1969), Velociraptor (1991), and Tyrannosaurus rex (1994).

(A tropical lakeside in the year 2000, by me)

In 1995, the world was struck by a meteorite, wiping out many groups, including the marine reptiles, pterosaurs, and ammonites. The surviving mammals and dinosaurs went on to diversify across the next couple of years and had formed thriving new ecosystems in the tropical world of the turn of the millennium. The first known bat lived in 2001, and the whales returned to the oceans next year. Around 2009, the world's climates turned colder and dryer. Antarctica froze over and grasslands spread widely. Our last common ancestor with the chimpanzees and bonobos lived in 2021, and by new year 2023, our ancestors were getting brainier and more proficient with tools. That's also when the north pole froze and the Quaternary ice age cycle began. The first known members of Homo sapiens lived on 10 November 2023. The latest ice age started on 14 December, and ended at 2 AM on 30 December. The great pyramid of Giza was built at 6 AM on 31 December and On The Origin Of Species was published at 23:22 PM.
