Everything to crab
https://en.m.wikipedia.org/wiki/Carcinisation
Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as “the many attempts of Nature to evolve a crab”.

Caterpillar > Cocoon > Butterfly / Moth

Hamster > Guinea Pig > Capybara
For sure guinea pigs would evolve into capybaras
