Evolution's Crabby Sense Of Humor

Evolution's got a twisted sense of humor! Instead of blessing us with superintelligent octopus overlords or dolphin professors, it keeps churning out more crabs. Carcinization—the bizarre evolutionary phenomenon where everything eventually evolves into crab-like forms—is nature's way of saying "when in doubt, crab it out." Five separate lineages have independently evolved into crab-shaped creatures because apparently that body plan is just *chef's kiss* for survival. Meanwhile, scientists are over here smashing the red button like "PLEASE, JUST ONE INTELLIGENT SPECIES THAT ISN'T A MAMMAL OR OCTOPUS." Mother Nature: "Best I can do is another sideways-walking pinchy boi."
