We are living in an era of environmental change with undeniable parallels with past mass extinctions. To improve our understanding of planetary health and resilience, we must expand our research beyond traditional lab models. Forecasting the future of biological diversity relies on extrapolation of past trends, which necessitates the study of a wider range of biological systems. The ‘Unconventional and Emerging Experimental Organisms for Cell and Developmental Biology’ meeting, which took place in Dorking, UK, in September 2023, emphasized the importance of this broader approach. Discussions centered on evolutionary innovation, robustness and diversity, underscoring the need for broader taxon sampling and novel experimental models to address current and future challenges.
