Darwinistic evolution of species started on the level of molecules. It is still unknown under which conditions evolution of molecules of increasing complexity can occur in chemical mixtures that are out of thermodynamical equilibrium. We examine a simple scenario, in which molecular units assemble into chains either by spontaneous or by template-driven, assisted concatenation. We show that, beyond a critical rate of assisted concatenation, the fractions of chains of increasing length grow exponentially. An experimental realization of this system is proposed.
