The origins of microendemic adaptive radiations: from introgression to fitness landscapes
One of the most poorly understood evolutionary processes is the evolution of novelty. How do new species colonize novel ecological niches or begin to use existing structures for novel functions? This talk will explore the complex origins of trophic specialists in two case studies for the evolution of sympatric radiations and ecological novelty: Caribbean pupfishes and Cameroon crater lake cichlids. The answer lies at the intersection of ecological opportunity, performance, complex fitness landscapes, and diverse sources of genetic variation.
