Spontaneous Order

“The paper strips away the nitty-gritty details of cells and biology and describes a simpler, simulated system of chemicals in which it is nonetheless possible for exceptional structure to spontaneously arise—the phenomenon that England sees as the driving force behind the origin of life. ‘That doesn’t mean you’re guaranteed to acquire that structure,’ England explained. The dynamics of the system are too complicated and nonlinear to predict what will happen.

The simulation involved a soup of 25 chemicals that react with one another in myriad ways. Energy sources in the soup’s environment facilitate or ‘force’ some of these chemical reactions, just as sunlight triggers the production of ozone in the atmosphere and the chemical fuel ATP drives processes in the cell. Starting with random initial chemical concentrations, reaction rates and ‘forcing landscapes’—rules that dictate which reactions get a boost from outside forces and by how much—the simulated chemical reaction network evolves until it reaches its final, steady state, or ‘fixed point.'”
