All life, including cells and artificial protocells, must integrate diverse molecules into a single unit in order to reproduce. Despite expected pressure to evolve a simple system with the fastest replication speed, the mechanism by which the use of the great variety of components, and the coexistence of diverse cell-types with different compositions are achieved is as yet unknown. Here we show that coexistence of such diverse compositions and cell-types is the result of competitions for a… 
Compartmentalization and Cell Division through Molecular Discreteness and Crowding in a Catalytic Reaction Network
The reproduction of a localized cluster is demonstrated, that is, a protocell with a growth-division process emerges when the replication and degradation speeds of one species are respectively slower than those of the other species, because of overcrowding of molecules as a natural outcome of the replication.
Exponential growth for self-reproduction in a catalytic reaction network: relevance of a minority molecular species and crowdedness
This study emphasizes that the minority molecular species in a catalytic reaction network is necessary for exponential growth at the primitive stage of life.
