Hypercycles are claimed as a possible evolutionary precursor to living cells. They are an attempt to show how life can originate by natural process. They are hypothetical non-biological autocatalytic chemical reaction cycles of the substances thought to be needed for the spontaneous generation of life.
They are an attempt to extend Darwinian evolution to the origin of life.
The hypercycle. A principle of natural self-organization. Part A: Emergence of the hypercycle.
The idea is that these hypercycles would build up by mutation and natural selection all of the substances and ultimately the processes and structures of living cells. They are a purely and rather simple mathematical model that lacks any detail.
They are entirely hypercyccle with no apparent real world basis. Hypercycles are just another in the long line of Evolutionary eigne so stories that are invented to try to explain the origin of life by natural processes. The hypercycle model was a highly speculative schema proposed by Nobel Prize in chemistry, Manfred Eigen along with his graduate student Peter Schuster.
The hypercycle model is a particular class of self-replicative reaction networks and can be characterized by topological methods. Hypercycle elements should be simultaneously catalysts enzymes and replicators. They must have the ability to replicate itself and produce enzymes, that means, have a metabolism.

Only ribozymes, RNA molecules with catalytic functions,  possess these characteristics. The scheme is basically as follows: The information carrier I i a RNA matrix has the capability to instruct two things: One of the harshest criticism of the hypercycles scheme that is raised by biologists, including evolutionists, jypercycle the possibility or even the inevitability of mutants arise at any step of this process.
These mutants can act as parasites interrupting the cycle. For example, a mutant generated by ribozyme I 2 can still be catalyzed by the enzymes produced by I 1 but not longer be capable of catalyzing replication of the information carrier I 3 see figure beside.
Wicken the hypercycle theory is based on unwarranted assumptions about the conditions of prebiotic evolution and the eien of these assumptions run counter to both empirical evidence and to the rational by which natural selection operates in evolution generally.

The merits of hyperccle theory must therefore be assessed in somewhat indirect fashion, by considering its assumptions and predictions in light of what we know about the likely chemical conditions of prebiotic evolution and the rationale of natural selection.
However, complex hypercycles only exist as computer simulations. More than thirty years after the introduction of the hypothesis, there is no experimental evidence whatsoever for complex, possibly prebiotic hypercycles.
This hypeecycle them still nothing more than mere speculation and, while the hypothesis has been a recurring theme in the scientific literature about the origin of life, it is not frequently mentioned anymore in recent publications in the field.
