Long-term evolution on complex fitness landscapes when mutation is weak

Understanding evolution on complex fitness landscapes is difficult both because of the large dimensionality of sequence space and the stochasticity inherent to population-genetic processes.

Understanding evolutionary dynamics on general fitness landscapes remains an important project for theoretical population genetics

we still lack a general theory that would apply to finite polymorphic populations on complex fitness landscapes, making it difficult to address the types of questions we have considered here in that more realistic context.
