Crablike bodies are so evolutionarily favorable that they’ve evolved at least five different times

    It’s the same reason both bats and birds have wings.

    This article is trash. It’s been established for a long time that bats have wings to frighten criminals.

    the tasty king crab that’s coveted as a seafood delicacy, aren’t even technically “true crabs.”

    I’m not ready for this today.

          IANAS, but it sure seems like most of these pig fuckers just went fully off-road genetically as soon as their two main external sphincters formed during mitosis, and focused everything else afterward on that core concept: Eat & Shit. (punctuation optional; creative emphasis, arrangement, spelling, etc. promoted)

          They are, just like guinea pigs (their smaller relative). It’s just that the bauplan is rather close to a pig - stubby legs, roundy body, stubby tail.

          I guess that just like non-crustacean peak performance is to become crab-like, mammal peak performance is to become pig-like? Cats*, humans, dogs, we’ll eventually get porcinised!

          *except my cat. She’s a Schweinekatze (pig-cat) so she’s already pig-like.

    The big takeaway the casual reader should learn from this is that contrary to the memes it’s not “animals” it’s “crustaceans” and to some extent arthropods.

    Apes won’t evolve into crabs unless we do it deliberately.

That’s it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.
