Investigations by Stuart Kauffman
The heart of this view of the emergence of life lies in the fact that as the
diversity of organic molecules in a system increases, the diversity of
reactions by which they transform to one another increases very much faster.
In turn, this means that for a wide distribution of assumptions about which
molecules catalyze which reactions, at a sufficient diversity so many
reactions are catalyzed that a collectively autocatalytic set of molecules
is virtually certain to emerge. On this view, the emergence of collectively
reproducing systems of molecules is an expected phase transition in complex
chemical systems.
