autocatalysis
Let an agent explain autocatalysis, relay its kinetics, examples, autocatalytic sets and hypercycles and relevance to the origin of life from chemistry and origin-of-life sources with hypotheses attributed, describe the named concepts, and distinguish autocatalysis from ordinary catalysis, chain reactions and enzyme catalysis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain autocatalysis, relay its kinetics, examples, autocatalytic sets and hypercycles and relevance to the origin of life from chemistry and origin-of-life sources with hypotheses attributed, describe the named concepts, and distinguish autocatalysis from ordinary catalysis, chain reactions and enzyme catalysis.
A chemical reaction in which one of the products is itself a catalyst for the reaction, so that the reaction rate increases as product accumulates, giving a characteristic S-shaped or sigmoidal progress curve; related concepts the registry aliases name include autocatalytic sets, networks of molecules that collectively catalyse their own production, and hypercycles, proposed by Manfred Eigen, both important in theories of the origin of life. Autocatalysis appears in chemistry, biology and even some corrosion and clock reactions, and can cause runaway or oscillating behaviour.
What it is for: Self-accelerating chemical reactions.
It can be explain kinetics; relay examples; describe autocatalytic sets and hypercycles; relay origin-of-life relevance with attribution.
Distinguishing features
Product is a catalyst
Accelerating rate
Sigmoidal kinetics
Origin-of-life relevance
What it looks like
Not a physical object; seen as accelerating or oscillating reactions and sigmoidal curves.
Physical character
progress curve: sigmoidal note
hypercycle: proposed by Manfred Eigen note - 1970s
registry parent: chemical reaction note
How it is recognised
Reaction whose product catalyses itself
Autocatalytic set, hypercycle
Ordinary catalysis uses an external catalyst; chain reactions propagate via intermediates; enzyme catalysis uses proteins
