The Great Oxygenation Event and Its Legacy

This chapter examines the Great Oxygenation Event, a transformative period in Earth's history that enabled the emergence of complex life forms. It highlights the interplay between geological processes, biological evolution, and the crucial roles of nitrogen and phosphorus in supporting life. Furthermore, the chapter discusses how these changes initiated significant climatic shifts and set the stage for the Cambrian explosion and the resilience of life during extreme conditions.
