This schematic illustrates four central challenges in the field: (1) integrating cell biology with evolutionary theory and experimental evolution, (2) bridging the genotypeβphenotype gap, (3) identifying and developing new model systems, and (4) incorporating ecological context into evolutionary cell biology. Each quadrant highlights a conceptual hurdle that must be addressed to advance the discipline.
@gautamdey.bsky.social, @fritzlaylin.bsky.social, @alebenoit.bsky.social and @eelcotromer.bsky.social discuss how the field of evolutionary cell biology works to understand how cells evolve & diversify, highlighting current challenges & the future outlook.
