Calcium carbonate (CaCO3) biomineralizing organisms have played major roles in the history of life and the global carbon cycle during the last 541 Ma1. Both marine diversification and mass extinctions reflect physiological responses to environmental changes through time. An integrated understanding of carbonate biomineralization is necessary to illuminate this evolutionary record and to understand how modern organisms will respond to 21st century global change. Biomineralization evolved independently but convergently across phyla2, suggesting a unity of mechanism that transcends biological differences. In this talk will combine all we know about biomineralization from diverse organisms 3-5 into an integrated model for CaCO3 biomineralization applicable to all phyla. The model frames questions about the past, present, and future of CaCO3 biomineralizing organisms.
