Like tech bros repeatedly trying to invent a new type of transferral andaccidentally reinvent the bus , evolution seems to keep spitting out animals that expect like crabs . First mint as a termin 1916 , carcinization was originally defined as " one of the many try of nature to evolve a crab louse " .
Convergent evolutionis when similar features evolve in metal money from different periods or regions that have a alike form or function , despite the last usual root of the animals or plants not having that particular feature of speech . Think how echo sounding has evolved in both heavyweight and bat , and mechanics for escape evolve in birds , insects , flying reptile , and bats . ( Get your own evolutions , at-bat , take leave hogging up everyone else ’s ) .
As the video above explain , a tidy sum of thing you might reasonably call crab ( because they look and act like , well , crabs ) are n’t actually crabs , they just " evolved into something that expect like crabmeat . Independently . Over and over again . "
During the cretaceous menses tool that looked more lobster - ilk in form became more squashed , and their small back legs became long and more crablike . The advantage seems to be that the Cancer shape allows them to take the air and burrow more efficiently , with some crabs that can even climb trees thanks to the embodiment ( see the atrocious main image ) .
