Earth's history shows a connection between life and geology from "summary" of Earth in Human Hands by David Grinspoon

Earth's history is a complex tapestry woven with intricate connections between life and geology. The story of our planet's evolution is not just a series of random events, but a dynamic interplay between living organisms and the physical environment in which they exist. From the earliest microbes to the diverse ecosystems that now inhabit Earth, life has shaped and been shaped by the forces of geology over billions of years. The relationship between life and geology can be seen in the way that living organisms have influenced the composition of the atmosphere and the chemistry of the oceans. For example, the emergence of photosynthetic bacteria billions of years ago played a crucial role in transforming Earth's atmosphere from one dominated by carbon dioxide to one rich in oxygen. This shift in atmospheric composition had profound effects on the evolution of life on Earth, leading to the rise of complex organisms that rely on oxygen for their survival. Geological processes have also influenced the evolution of life in profound ways. The movement of te...
