We all know about carcinization: shelled creatures with many legs tend to evolve into crabs.But have you heard of mustelification?It's a phenomenon where carnivorans develop slender bodies, short legs and small triangular heads.In other words, they evolve into weasels. pic.twitter.com/A3TAOE3701— Creature of Culture (@aeranothaur) April 10, 2021
Oh I was hoping we were all evolving hardshells and would live in tidal pools.
