In addition to the transition phenomena mentioned so far in the present section, a variety of even larger scale processes might have operated during chemical evolution, namely, instabilities and bifurcations in the very atmospheric environment within which life emerged. As shown in the paper by Marcel Nicolet, the earth s atmosphere is the theater of a variety of complex chemical and transport phenomena. Moreover, as explained by Stanley L. Miller, the composition of the primordial atmosphere has certainly affected deeply the chemistry in the primitive oceans. Conversely, once life emerged the properties of the atmosphere changed radically, and this must have affected the further course of evolution. We refer to Prather et al.41 and North et al.42 for an account of present views on large scale transitions in the earth-atmosphere system. 

Aspects of chemical evolution XVIIih Solvay Conference on Chemistry, Washington, D.C., April 23-April 24, 1980. 

The first part of the Conference was devoted to the historical role of the Solvay Institutes, and in particular of the Solvay Conferences on Physics and Chemistry, in promoting international scientific cooperation. The second part was devoted to some aspects of chemical evolution. This subject comprises an impressive number of different, yet complementary, questions having an interest in their own right.

However, before bacteria could evolve, the fundamental chemistry of life needed to be established. For this we need to turn back the clock to around 4.5 - 4.1 billion years ago where the earth s crust has cooled and solidified and the oceans and atmosphere begin to form. It is speculated that iron-sulfide synthesis along deep oceanic platelets may have lead to the synthesis of the first RNA and self-replicating molecules. Exactly how this chemical evolution came about remains an open question. It is possible that RNA may have used clays and similar self-replicating materials as substrates. Eventually, this... 

The dynamic process is akin to the error checking mechanisms employed in protein synthesis each reaction is reversible until the correct product has formed. In any evolutionary chemical system it is important to ensure copying fidelity and the success of dynamic combinatorial libraries indicates that concepts associate with supramolecular chemistry can be valuable in advancing chemical evolution.
