That's only if the gene's to express an appendix ever go away.
I always think back to Richard Dawkins explaining how a particular vein in a Giraffe's neck is wrapped around a lower neck bone and has grown 2x to accommodate the long neck instead of regrowing in a more efficient way (not wrapping).

- roywiggins 5y agoThe recurrent laryngeal nerve is actually common to all tetrapods, not just mammals. Birds have it, probably dinosaurs had it. https://bioone.org/journals/acta-palaeontologica-polonica/volume-57/issue-2/app.2011.0019/A-Monument-of-Inefficiency--The-Presumed-Course-of-the/10.4202/app.2011.0019.full https://bioone.org/journals/acta-palaeontologica-polonica/vo...
