Dysons Origins of Life

A computer simulation carried out by C. Kuhn (2001) was able to confirm certain critical phases in the first steps of Kuhn s theory, such as the formation of aggregates (collector strand and hairpin strand). In this simulation, the process of the development of a simple genetic apparatus took place in three stages  

Construction, i.e., simulation of the formation of aggregates, and diffusion and fitting together of the molecular strands. 

The multiplication phase the aggregates fall apart to give single strands, which now act as matrices. Complementary copying occurs, accompanied by a number of copying errors. Matrix and replication strand separate. 

Kuhn s biogenesis models were developed further (Kuhn and Kuhn, 2003). The basic principle remains unchanged replication first As before, no exact single steps are elaborated, but only the main aspects of the biogenesis process are dealt with. 

The authors suggest that it was the structural diversity of the environment which made biogenesis possible in other words, there was an enormous selection of regions with different properties and states on the young Earth which acted as stimuli for the increasing complexity of the evolving systems. As complexity increased, those regions of the primeval Earth which were not available for earlier, more primitive systems could be colonized .
