(PDF) Carcinization in the Anomura - Academia.edu Carcinisation (or carcinization) is an example of convergent evolution in which a crustacean evolves into a crab-like form from a non-crab-like form.The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "one of the many attempts of Nature to evolve a crab". The generic name is a combination of McLaughlin's preferred first name and the Greek word pagourus (a kind of crab), which was the origin for the nominal pagurid genus, Pagurus Fabricius, 1775.Specific epithet referring to the extraordinary albeit . .
