Increasing complexity of linear, prevailing, autocatalytical molecules — •Philipp Zimmer1, Emanuel Gregor Worst2, Eva Wollrab2, Albrecht Ott2, and Karsten Kruse11Universität des Saarlandes, Theoretische Physik, Postfach 151150, 66041 Saarbrücken — 2Universität des Saarlandes, Biologische Experimentalphysik, Postfach 151150, 66041 Saarbrücken

Two common concepts of Darwinian evolution are mutation and selection. In natural evolution, these processes have permanently generated increasingly complex species. Nevertheless evolution has maintained to avoid dead ends such that a further development is proceeding. This process is not well understood. Performing stochastic simulations as well as experiments with DNA, we find that our system evolves reproducibly towards consecutive states of increasing complexity, if the autocatalytic activity exceeds a critical value.
