Earth and Life through Time

This course investigates the history of Earth as a dynamic, interconnected system reconstructed from the geologic record. Students examine how interactions among the geosphere, hydrosphere, atmosphere, and biosphere drive change through time. Emphasis is placed on analyzing scientific evidence, interpreting data, and evaluating competing explanations for major transitions in Earth and life history, including mass extinctions, climate change, and evolutionary radiations. Students apply scientific reasoning to reconstruct past environments and consider how insights from Earth history inform our understanding of contemporary environmental challenges. Pre- or co-requisites recommended: EMES 101 , 200 or 201 .
