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 ...

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 ...

Pathways of Chemical Evolution of Photosynthesis

Origins of Life, 1974
The primary metabolism of protobionts was probably based on the electron transfer reactions regulated by catalysts or photosensitizing pigments. The action of photoreceptive pigments was inevitable in the case of electron transfer leading to light energy storage in the reaction products.

A chemical systems approach to evolution

RENDICONTI LINCEI, 2007
A novel approach to the evolution of organisms is given. It asserts that biological evolution was consequential upon geochemical, environment, change and was inevitable not accidental.
