Which event in earths history was dependent on the development of a certain type of life-form?
The Great Oxygenation Event, which occurred around 2.4 billion years ago, was heavily dependent on the development of photosynthetic cyanobacteria. These microorganisms produced oxygen as a byproduct of photosynthesis, significantly increasing atmospheric oxygen levels. This shift not only altered the planet's atmosphere but also paved the way for the evolution of aerobic organisms and complex life forms.
