I might be misunderstanding but isn’t that how this works? As I understand it carcinisation doesn’t actually turn for example lobsters into crabs, it just makes them crab-shaped
Exactly. The meme doesn’t say that they turn into crabs but uses the correct term of carcinisation. Tree is a term about morphology, nothing to do with clades. So snakes is the odd one out because it does describe a monophonic group. Lizards don’t turn into snakes, they just look like them.
