Even if we take a ‘replicators first’ view of the origin of life, we still have to explain how a chemical environment arose that was sufficiently diverse for such replicators to be formed. As a minimum, we must explain the abiotic formation of sugars and amino acids, and of nucleotides or of some simpler molecules capable of base pairing, and hence of ...

Evolution was Chemically Constrained
Journal of Theoretical Biology, 2003The objective of this paper is to present a systems view of the major features of biological evolution based upon changes in internal chemistry and uses of cellular space, both of which it will be stated were dependent on the changing chemical environment.

Chemical Evolution of Galaxies
Annual Review of Astronomy and Astrophysics, 1976The various nucleosynthetic processes needed to account for the formation of the different nuclear species have been described in the previous chapters as well as the location of these nucleosynthetic events. At the beginning of this monograph, the evolution of the matter which constitutes the celestial bodies such as planets, stars and galaxies was ...

Chemical evolution of photosynthesis
Origins of Life, 1976The principles of biological evolution of photosynthesis are established, but the ways of chemical evolution are unclear yet. The model systems will help to elucidate the problem. Every type of photosynthesis requires photoreceptor absorbing solar radiation. We studied as photoreceptors inorganic components of Earth crust, some coenzymes and porphyrins

Chemical methods such as directed evolution and some forms of the SELEX procedure implement evolutionary algorithms directly in vitro. They have a wide range of applications in detecting and targeting diseases and potential applications in other areas as well [1].
