carcinisation
I think carcinisation is bullshit. You can find out what it is on wikipedia:
https://en.wikipedia.org/wiki/Carcinisation
page 400
"the sister group to Anomura is now widely accepted as Brachyura, the two clades constituting Meiura"
page 93 contains a nice image illustrating this
Based on this, all crabs are monophyletic, as all crabs are in either anomura or brachyura, and it is most reasonable to assume they evolved from a proto-crab. This means carcinisation is bullshit.
