An emerged autocatalytic set, draining the racemate ursoup of one
enantiomer by metabolizing it and incorporating it into self. It did not
matter which of them, R or S. Since it was capable of autoamplification,
it amplified a random nanoscale event to macroscale.

The other enantiomeres in the pool were sometimes coupled via racemisation
reactions, and were generically not inert to the suddenly changed global
chemistry. The emerged autoreplicator changed the context, and made
emergence of new ones impossible.
