In this Gordon Research Conference “The Processes of Geobiological Evolution on a Living Planet”, we will explore the mechanisms that have enabled life to thrive and survive at the surface of the planet for more than 3.5 billion years, the roles that theory and evidence play in understanding the record of co-evolution on a living planet, and new approaches from sibling fields to Geobiology allow us to explore these ideas further. The Gordon Research Seminar “New Insights on Ancient and Modern Interactions Between Organisms and Their Environments” is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting-edge ideas. The GRS speaker abstract deadline is August 7, 2022; the GRS application deadline is October 8, 2022. The GRC application deadline is October 9, 2022.
