Pawns, Prawns, and... Crabs? A Journey of Carcinization - How?Fascinating! ep.61

Jun 06, 2021
hello interwebs and welcome back to the


thing you may remember that in episode 39 we touched on the names of the chess pieces and it turns out that I shouldn't have taken my finger off them because I have since learned that each of the eight


also have their occupation itself, the player, who is a common criminal, goes to the far left and the most sinister position literally next to him is the city guard or the policeman in front of the knight because historically the knights trained the city guard. city ​​actually. the next life is the innkeeper in front of the bishop, followed by the merchant and the doctor, the king's money changer and the queen's personal position respectively, the weaver or the scribe is in front of the other bishop for whom they weave the clergyman in front of the other gentleman. the blacksmith who made armor for the night or horseshoes for his horse and the last one is the farmer in front of the castle of which he was a vassal, what a nuisance.

I have also heard that the laborers refer humorously to


. Previously we established that the word. peon comes from the Latin word pedone which means foot soldier, but gamba comes from Middle English prain and we have no idea what its etymological origin is. It seems to have emerged at the beginning of the 15th century and does not present clear cognates in any separate language. from English according to the Oxford English Dictionary a similar name is not found in other languages ​​in Australia prawn is also slang for an idiotic or foolish or naive person and this is from once we get the phrase comes the raw prawn which means to play the role of The Fool Who Talks About Shellfish we also established in the previous episode that it is not a scientifically valid term as it refers to both crustaceans and bivalves which belong to separate phyla as it cannot be answered scientifically.

More Interesting Facts About,

I have a philosophical question for you, dear viewer. sea ​​turtles shellfish I say no because arthropods and mollusks belong to the protostomia clade while reptiles like sea turtles are vertebrates and therefore belong to the deuterostomia plate my girlfriend also says no because sea turtles must surface to breathe, that said, there are still sea animals with shells, so let me know what you think in the comments. Lobsters are definitely shellfish even though they do not have true shells and they are not fish because there is no such thing as fish. Also, strictly speaking, arthropods have kitesan exoskeletons, not shells.

Shells are calcareous bone-like structures, which means they contain calcium carbonate. However, restaurants still market lobsters as seafood, so tell me which are the two tastiest parts of one. I assume you said the claws on the tail or, if you're feeling cheeky, the left claw. and the correct claw, both answers are incorrect because lobsters do not have claws or tails. True claws are made of hardened keratin and are only found at the ends of the fingers in amniotes such as mammals and reptiles which, as a reminder, include birds, certain arthropods such as lobsters. and scorpions on the other hand have what is known as kili and the legs that end in these structures are called kilopeds the tail of a lobster is its abdomen and real tails are exclusive to vertebrates while we are on the topic of which animal moves Mainly lobstering, I know. what you're thinking, but despite the name, the correct answer is actually lobster with shrimp, more accurately known as paradoid escape reaction, is a type of swimming movement used by long-bodied crustaceans such as shrimp, krill and the river crab.

Lobsters can also use this technique. going towards its extended abdomen and tail fan, but its main form of locomotion is walking along the sea floor like a crab rather than swimming in the water like a shrimp. In fact, lobsters are a species of intermediate evolutionary phase in which shrimp become


like Shrimp have approximately cylindrical bodies with long abdomens and antennae, while


have wide, flat shells and short antennae, but unlike Of the shrimp that have pleopods adapted for swimming, lobsters of the nephropodai family have powerful claws and robust legs adapted to walk like crabs, although they walk forward. instead of sideways and are still able to back up like a shrimp.
Also, I said that shrimp become crabs and not the other way around because that's how it has developed historically. Modern crabs evolved from more shrimp-like ancestors and are not alone in this


. What Voyager would have you believe with its giant salamander monsters and sci-fi so smooth you can spread it on toast and call it breakfast, evolution doesn't have a predetermined path or even a destination, but if it did I'd probably be a crab, I say. this because things have turned into crabs so many times that the phenomenon has its own special name carsonization in simple terms this is when a species evolves into a crab-like form from a non-crab-like form kyler virkner and richter established the following three morphological ratings in 2017. one, the carapace is wider than it is tall, two, the sternites are fused into a single plastron, and three, the abdomen or pleon is dramatically flattened and curved below the cephalothorax.
This transformation has occurred at least five times. In the evolutionary history of decapods alone, in addition to the infraorder brachiora of true crabs, it also occurred no less than three times in animorines. Do you realize what that means? It means that this is the ideal male body. You may not like it, but this is what maximum performance means. It seems like a special mention, however, you have to go to the cyclinas. These round guys evolved a crab-like morphology in the Carboniferous period before crabs cooled off, which basically turns them into pre-ccr hipsters. No, I'm not talking about credibility, I'm talking about the Cretaceous.
Crab revolution: This was a major biological diversification event that occurred during the Cretaceous period around 145 to 66 million years ago and gave rise to approximately four-fifths of modern groups of crabs, including the oldest known true crab, aeoprosupon kluge, the crab wannabes in the infraorder. Anamora include hermit crabs, king crabs, coconut crabs, porcelain crabs and hairy stone crabs, and the phenomenon can also be observed to a lesser extent in yeti crabs and horseshoe crabs, the latter of which are not even crustaceans but arachnids, even blood-sucking parasite theorists. The pubes have enough similarity to have earned the colloquial name crabs, so why do things keep evolving into crabs?
To be honest, we can't say for sure that a shorter pleion has been theorized to be one less tasty appendage for potential predators to grab and the reduced overall body length leads to greater mobility; Just compare the versatility of a smart car to that of a 12-passenger van that my friend once complained had the turning radius of a small building at the highly crab-like end of the false crab spectrum we know. . Cases of hyper


can even be seen, for example, in addition to their shortened carapace, members of the species allopetrolistes spinifrons also exhibit a crab-like sexual dimorphism in which the pleions of males are shorter than those of females. , there are species of porcelain crab that are closely related. to crab-like lobsters, by the way, I now have the perfect insult for a sunburnt gopnik and, speaking of ethnic stereotypes, I used to joke with my Italian friend that his ancestors evolved from crabs , since their homeland has vast stretches of rocky coastline and they communicate with wild gesticulations of their forelimbs now I see I was wrong the Italians did not evolve from crabs they are evolving into crabs an even more pronounced case of human carsonization can be seen in the Professional arm wrestler matthias hellboy schlitte, who may be the first step in our species slowly transformed into fiddler crabs, that was obviously a joke, but it's not as ridiculous as it may seem at first.
You see his career as a result of his notable asymmetry, not the other way around, since many people assume Schlitte was born with rare genetics. bone disorder that makes his right forearm drastically larger than his left, so he took up competitive armwrestling and became the youngest winner of Germany's biggest tournament and has amassed eight German national championships and 14 International championships, I guess. life gives you lemons, make lemonade and when life turns you into a crab, become an arm wrestler, joking aside, his unusual status has made him a minor celebrity and thus increased his social status in In evolutionary biology, this often goes hand in hand with monstrously huge size with increased reproductive fitness. i.e. the ability to pass genes on to the next generation, in a nutshell, that's exactly how we would evolve into crabs, so maybe we should accept the inevitable, basically, in a long enough timeline, everything will come together. turns into a crab, even the theme of this video started as chess. pieces, but now we are talking about things that become crabs in a perfect example of what xkcd has called metacarsonization.
If you enjoyed it, you should follow me on Twitter, where I cultivate a running thread of jokes about Carsonization and just getting things back to normal. To start, there is a strategy in chess known as the crab opening. Thanks for watching and have a
