Conventionally, evolution has always been described in terms of species. The Chemistry of Evolution takes a novel, not to say revolutionary, approach and examines the evolution of chemicals and the use and degradation of energy, coupled to the environment, as the drive behind it. The authors address the major changes of life from bacteria to man in a systematic and unavoidable sequence, reclassifying organisms as chemotypes. Written by the authors of the bestseller The Biological Chemistry of the Elements - The Inorganic Chemistry of Life (Oxford University Press, 1991), the clarity and precision of The Chemistry of Evolution plainly demonstrate that life is totally interactive with the environment. This exciting theory makes this work an essential addition to the academic and public library. *Provides a novel analysis of evolution in chemical terms *Stresses Systems Biology *Examines the connection between life and the environment, starting with the 'big bang' theory *Reorientates the chemistry of life by emphasising the need to analyse the functions of 20 chemical elements in all organisms.

... He noted that many microorganisms, such as certain algae and protozoa, show a directional bias and tend to swim upward. As these organisms concentrate near the upper surface of the fluid, they create a top-heavy, unstable density distribution, which in turn leads to convection, where denser fluid (containing more organisms) sinks, while less dense fluid rises, creating circulation patterns that resemble the Benard cells typical of thermal convection (hence the term bioconvection pattern) [3,4]. The requirement of a minimum critical depth and a minimum critical density for pattern formation support the resemblance to Benard cells, with the density of motile organisms being the analog of the energy input in the thermal case [5][6][7]. ...
