One example of a life-form in the Precambrian time was cyanobacteria, which are ancient photosynthetic bacteria thought to be one of the earliest forms of life on Earth. Cyanobacteria played a crucial role in the Great Oxygenation Event by producing oxygen as a byproduct of photosynthesis, which significantly altered Earth's atmosphere.

The earliest forms of life likely used anaerobic respiration, which does not require oxygen to produce energy. This process is less efficient than aerobic respiration but can still generate ATP for cellular processes.

All land animals evolved from under the water. I would say fish and ammonites.
