autocatalysis

 [aw″to-kah-tal´ĭ-sis]
an increase in the rate of a chemical reaction in which a product of the reaction itself hastens or intensifies the rate.

au·to·ca·tal·y·sis

(aw'tō-kă-tal'i-sis),
A reaction in which one or more of the products acts to catalyze the reaction; after beginning slowly, the rate of such a reaction rapidly increases. Compare: chain reaction.
Synonym(s): autoactivation

autocatalysis

/au·to·ca·tal·y·sis/ (-kah-tal´ĭ-sis) catalysis in which a product of the reaction hastens the catalysis.

au·to·ca·tal·y·sis

(aw'tō-kă-tal'i-sis)
A reaction in which one or more of the products formed acts to catalyze the reaction; beginning slowly, the rate of such a reaction rapidly increases.
Compare: chain reaction

Deacon suggests that the interdependent combination of two morphodynamic processes, namely that of autocatalysis and the crystal-like "self-assembly" such as produces viral shells or cell membranes, can produce a simple form of molecular teleodynamics.
The trick is how to get these two morphodynamic processes, autocatalysis and membrane construction through self-assembly to co-emerge.
The reciprocal complementarity of these self-organizing processes means that spontaneous linkage of autocatalysis with self-assembly containment is a possibility [that] creates the potential for self-repair, self-reconstitution, and even self-replication in a minimal form, (ibid.
The way in which the two morphodynamic processes of autocatalysis and self-assembly could become self-supporting and create a teleodynamic system (that Deacon calls an autogen) is if the by-products of the autocatalysis were the components for self-assembly and, reciprocally, the by-products of self-assembly were the components for autocatalysis.
In a certain sense, the two morphodynamic processes of autocatalysis and self-assembly that give rise to teleodynamics are symbiotic.
Teleodynamics of the Autogen Arises from the Two Complementary Morphodynamic Processes of Autocatalysis and Self-Assembly
The emergence of living organisms and the teleodynamics that characterize them according to Deacon's model involved the co-emergence of two morphodynamic processes, autocatalysis and the self-assembly of a cell wall.
The social cohesion parallels the self-assembly part of the teleodynamics of the autogen in Incomplete Nature and the daily practices or habits parallel the autocatalysis component.
Paralleling the teleodynamics of an autogen, the semantics or vocabulary acts like autocatalysis providing the basic stuff out of which a language is built and syntax, like self-assembly, provides the structure or framework that keeps the language together.
No examples of possible autocatalysis playing a role in the evolution of non-human organisms are given, although this is forgivable since the book is about human evolution.
The literature has offered several explanations to the autocatalysis of the AAPCL.
The former decreased the autocatalysis and the latter decreased the kinetic constant.
