Molecular fossils, mass extinctions and the rise of complex algae

点击翻译按钮获取中文摘要

This project aims to illuminate the fate and role of phytoplankton during the Permo-Triassic crisis, the most severe mass extinction event in Earth's history. Despite being the vital driving force of the carbon cycle, these microscopic yet essential organisms have largely evaded fossilization and their precise history remains unknown. Leveraging innovative molecular fossil technology, this project seeks to unlock this critical information, generating insights into the mechanisms behind climate-driven mass extinctions and the subsequent recovery of marine life. By doing so, this study aims to reveal how current disruptions to the base of the food chain may escalate through all levels of marine ecosystems, causing extinction.
