Eran Agmon: Adaptivity in a protocell model

In this talk, the relationship between viability, ontogeny, and adaptivity is investigated in the context of a model protocell that emerges within an artificial chemistry. A network of possible ontogenies that the protocell can undergo is uncovered by subjecting the model protocell to sequential perturbations, and mapping the resulting structural configurations. The analysis of this network reveals trends in how the protocell can move between configurations, how its morphology changes, and how the role of the environment varies throughout. Viability is defined as expected lifespan given an initial configuration. This leads to two notions of adaptivity: a local adaptivity that addresses how viability changes in plastic transitions, and a global adaptivity that looks at longer-term tendencies for increased viability.
