Animals Keep Evolving Into Crabs, Which Is Somewhat Disturbing
We knew the long quarantine was making us all crabby, but this is extreme: People now feel fully betrayed by the long history of crabification (technically, “carcinization”) of different species over time. That means groups of crustaceans have evolved into crabs in five completely different contexts, giving rise to a meme that the long arc of history truly bends toward the crab.
So how does carcinization happen? Well, that part is pretty simple. Animals that live in similar habitats face obstacles that can shuttle them all toward the same evolutionary advantages. Britannica cites the marsupials as a key example, where despite having one critical difference from their “placental” counterparts in other parts of the world, the marsupials often correspond very closely to these other animals.
Animals can evolve separately but end up evolving toward other species, too, or even spontaneously evolve the same characteristics in totally separate groups. Birds and bats can both fly using mechanical wings. Birds and mammals are both warmblooded, but both evolved from groups that were not.
