Why Does EVERYTHING Evolve Into Crabs? Why does evolution keep turning totally different animals into crabs? No, seriously. Evolution has independently created the crab body shape at least five separate times, and scientists still don’t fully know why. This video dives deep into carcinization, convergent evolution, prehistoric crab species, and the bizarre secrets behind one of nature’s most persistent—almost obsessive—design choices. From hermit crabs turning into king crabs, to ancient reef predators with crushing claws, to a 95-million-year-old crab with giant baby-like eyes, we’re breaking down 200 million years of crab history. We explore how true crabs and false crabs evolved, why this body shape keeps reappearing, and what it actually gives animals in terms of survival advantage. Spoiler: nature basically speedruns the same solution over and over because it works.
