Forget carcinization. Limpets are the true convergent evolution queens 👑

I'm a marine biologist who spent years reading limpet shells for palaeoclimate and archaeological research.

Carcinization gets all the memes, but the independent evolution of the limpet body plan happened in vast number of separate gastropod families, over 500 million years.

I wrote about why it keeps happening, how it fooled taxonomists for decades, and how one lineage even managed to re-coil, challenging Dollo's law.

Happy to discuss!
