A Guide to Rodent Phylogeny

If you'd told me that my first spiritual successor to The Cartoon Guide to Vertebrate Evolution would be about rodents, I wouldn't have believed you either. However, between Rodent Week on Twitter and a secret project* I've been working on, I've had rodents on my mind a lot lately.

*No longer a secret.

This diagram covers most extant rodent lineages, though I left out a few "minor" groups (usually consisting only of a few poorly-studied species). Nothing is to scale (except the capybara and guinea pig, roughly). Despite accounting for about 40% of extant mammalian species, rodent diversity frequently goes underappreciated, but I think many species are ecologically and evolutionarily very interesting... for mammals, at least.

To address the inevitable "Which group will you cover next?" and "Will you do X group?" questions, it's all up in the air for now. I made this very much as a spur-of-the-moment thing; whatever is next in the series (if anything) will likely be borne out of similarly fortuitous circumstances.

is there any minor groups you looking back think you should have included
