Meeting Summary: The goal of this working group is to address the onset of adaptive evolution in a prebiotic context. What theories or models of evolution allow selection-like processes to begin prior to genetic inheritance systems, and what spatial contexts do these models require (from wellmixed systems, to 2D-arrays, to protocells)? We will discuss existing theories, as well as needed evolutionary frameworks to understand how chemical systems became biological systems. Can we use evolutionary theory to guide the design of experiments aimed at understanding how systems become capable of making the transition from the abiotic to biotic? What are missing components of evolutionary theory and experimental design for realizing systems that can make this transition?
