Abstract
Adaptations that give rise to new biological functions are often complex, emerging through the interaction of multiple mutations. A complex adaptation may require a set of mutations that are beneficial only in combination. To adapt, a lineage must acquire mutations that are individually neutral or deleterious before gaining the beneficial combination, thereby crossing a plateau or valley, respectively, in the mapping from genotype to fitness. This thesis explores how spatial population structure affects the rate at which populations adapt across fitness valleys and plateaus through the analysis of theoretical models of populations that are subdivided into discrete subpopulations linked by migration.
