Query: A Driven Disordered Systems Approach to Biological Evolution in Changing
  Environments   Biological evolution of a population is governed by the fitness landscape,
which is a map from genotype to fitness. However, a fitness landscape depends
on the organism's environment, and evolution in changing environments is still
poorly understood. We study a particular model of antibiotic resistance
evolution in bacteria where the antibiotic concentration is an environmental
parameter and the fitness landscapes incorporate tradeoffs between adaptation
to low and high antibiotic concentration. With evolutionary dynamics that
follow fitness gradients, the evolution of the system under slowly changing
antibiotic concentration resembles the athermal dynamics of disordered physical
systems under quasistatic external drives. Specifically, our model can be
described as a system with interacting hysteretic elements, and it exhibits
effects such as hysteresis loops and memory formation under antibiotic
concentration cycling. Using methods familiar from studies in this field, we
derive a number of analytical and numerical results. Our approach provides a
general framework for studying motifs of evolutionary dynamics in biological
systems in a changing environment.
