Simulating chemical evolution

2011 IEEE Congress of Evolutionary Computation (CEC), 2011
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].

Evolution was Chemically Constrained

Journal of Theoretical Biology, 2003
The 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, 1976
The 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 the Galaxy

Annual Review of Astronomy and Astrophysics, 1991
Since the discovery of the cosmic microwave background ( 1 84), it is gen­ erally assumed that the universe originated from a hot big bang (78). Detailed nucleosynthesis calculations based on the hot big bang model (e.g. 4, 1 82, 221 ) showed that no element heavier than 9Be could have been synthesized primordially with an abundance exceeding 101 4 by ...

Chemical evolution and the evolution of the Earth's crust

Origins of Life, 1977
It is hypothesized that there is a close relationship between the geologic evolution of the global plates of the Earth's crust and the chemical evolution of life on the Earth. Characteristics of the axes of plate spreading are discussed in relation to postulated environments conductive to the synthesis of chemical compounds thought to be important ...
