Faecal microbiota richness is considered a hallmark of gut health and stability. However, in healthy hosts, richness would primarily reflect the stage of ecosystem development through the gut, rather than community resilience. This Comment discusses the need to rethink microbiome biomarkers in the context of gut ecology.
