During Precambrian time, one of the major events was the formation of the Earth's first stable crust and the development of the atmosphere and oceans. This era also witnessed the emergence of early life forms, primarily simple single-celled organisms like bacteria and archaea. The appearance of photosynthetic cyanobacteria around 3 billion years ago played a crucial role in oxygenating the atmosphere, leading to the Great Oxygenation Event. These developments laid the groundwork for more complex life forms that would emerge in later geological periods.

What was a major change that occured on earth during the Precambrian era?
During the Precambrian era, a major change was the emergence of photosynthetic organisms, particularly cyanobacteria, which significantly altered Earth's atmosphere by producing oxygen. This event, known as the Great Oxygenation Event, occurred around 2.4 billion years ago and led to the gradual accumulation of oxygen in the atmosphere. This increase in oxygen levels paved the way for the evolution of more complex life forms and fundamentally transformed Earth's ecosystems.
