Figure 6From: Spatial aspects of prebiotic replicator coexistence and community stability in a surface-bound RNA world modelDesorption of small molecules from the surface. The surface binds molecules A and B at time t. Energy input might detach them from the surface and they either reattach at another location (A) or leave the surface (B) by time t + 1, depending on the energy input (E 1 < E desorption threshold < E 2 ).Back to article page
