While all six properties of life are significant, biologists today regard evolutionary adaptation as the most fundamental and unifying of all. The growth and development of living organisms depend on factors such as heredity and environment. Water bridges the gap to life, so water makes it The product of some 4.6 billion years of cosmic construction, our planet is flush with life thanks to a fortuitous set of conditions. But why? Many substances dissolve in water due to its configuration of hydrogen and oxygen atoms. The system consists of the land, oceans, atmosphere and poles. Too close, and the water would rapidly, The interstellar cloud of gas and dust that gave rise to, Earth contained enough radioactive elements to power a, churning core for billions of years. Oxygen was thus the first major cause of extinction on Earth, but at the same time it was the engine of life, a turning point in the course of evolution that would give rise to multicellular beings and the explosion of life as we know it today, enormously diverse and complex, a cosmic lottery in which, at least as far as we know, only a first prize has been awarded.
