ABSTRACT
Water is fundamental to all life. As we will discuss in Chapter 8, life itself evolved in water, and all biochemical reactions take place in an aqueous or water environment. Environments that are totally lacking in water will be devoid of living things. If water is present, it is likely that life will be present as well. For instance, researchers have found microorganisms in pockets of liquid water over 10 meters deep in frozen Antarctic lakes, in boiling hot oceanic volcanic vents, and even in water vapor found in clouds.
