Life and surface environments co-evolved in symbiotic tandem: biological changes modified surface environments; in turn, independent changes in surface conditions triggered biological innovations. Superimposed on this complex relationship is the long-term control by plate tectonics and episodic perturbations by short-lived mantle plume events. If we want to understand Earth's evolution in the past and predict future global long-term changes, we should explore how the Earth's System behaved during transient periods between long-lasting, steady states. Capitalizing on my long-term involvement with early Earth's evolution, I will focus my own and my group's research for the next funding cycle on the key events and time intervals in the Earth's history to address remaining uncertainties about the evolution of surface environments.

生命与地表环境在共生串联中共同进化：生物变化改变了地表环境；反过来，表面条件的独立变化引发了生物创新。叠加在这种复杂关系之上的是板块构造的长期控制和短期地幔柱事件的偶发扰动。如果我们想了解地球过去的演变，并预测未来全球的长期变化，我们应该探索地球系统在长期稳定状态之间的短暂时期是如何表现的。利用我对早期地球演化的长期参与，我将把我自己和我的团队在下一个资助周期的研究重点放在地球历史上的关键事件和时间间隔上，以解决关于地表环境演化的剩余不确定性。
