When did liverwort oil body cells originate? Here, Susan and I provide quantitative evidence that they emerged by at least the Middle Devonian (~390 Ma!), shedding light on a key anti-herbivory defense mechanism of early land plants!

Happy to see this out! We describe a patterning mechanism underlying rhizoid specification in Marchantia. Contrary to classic patterning mechanisms (e.g., Turing), rhizoid specification depends on both randomness and lateral inhibition, involves subcritical bifurcations, and occurs at criticality!
