Inorganic Polyphosphates in Chemical and Biological Evolution

However, despite the outstanding achievements of evolutionary biochemistry, many problems still await solution. Among these unsolved and relatively little-investigated problems of evolutionary biochemistry, there are the role of phosphorus compounds in chemical evolution, which preceded the appearance of life on Earth, and the evolution of phosphorus metabolism from primitive organisms to contemporary living creatures.
