The ancestors of modern bacteria were unicellular microorganisms that were the first forms of life to appear on Earth, about 4 billion years ago. In a laboratoy, bacteria are grown from a solid or liquid material.

Bacteria is not actually caused, it exists in nature. Bacteria is sometimes caused to grow with temperature changes or with the introduction of food to an environment.
