In its simplest form, ... The process could go like this:
Catalyst A produces a chemical that catalyst B uses. Now, since B normally
seeks out this chemical, sometimes B will be attracted to A -- if its
desired chemical is not otherwise available nearby. As a result, A and B
will come into proximity, forming a complex.
Catalyst B normally 'seeks out' its substrate? Wow. That is one smart,
well motivated molecule!
One hopes this was metaphor. But metaphor for what??!!
JE:-
It appears to me to be a metaphor for the evolution of fitness independent
systems. If the two molecles concerned remain in close enough proximity by
chance e.g. within a membrain bound system, and this helps maintain the
complex as a single system for longer then natural selection will select for
it even if the system cannot reproduce itself. In other words survival can
be evelvated to become the fitness maximand of the system (the one thing
which always pertains to a maximum without exception, within each competing
system) in the absence of reproduction. However, once the reproduction of
the entire system becomes a reality the fitness maximand must move from just
survival to the reproduction of each system. The next stage is the
evolution of fitness interdependent systems, i.e. the evolution of
independent but entirely fitness mutualized systems via their continued
association within optimal sized groups. Here each group can act as a
powerful selective force on each individual system (known as the Baldwin
effect) but not as one grouped selectee (a grouped thing being selected) as
was incorrectly assumed by classical group selection.
