Insights into evolutionary diversification from genomic data: lessons from fishes near and far.

Recent technological advances have enabled our ability to collect population-level genomic data from many populations and species at once. These data have revolutionized our ability to answer detailed questions about the evolutionary history of rapidly evolving groups. In particular, these new data stand to break down traditional barriers between work at the population genetic scale and work at phylogenetic scales. I will discuss research utilizing population genomic analyses to shed light on broader patterns in evolutionary diversification using case studies from several freshwater fish groups. These will include case studies from afar—the fishes of Lake Tanganyika in East Africa, a ~10 million year old lake basin; as well as those much closer—trout in the US mountain west, introduced to previously fishless alpine lakes only ~100 years ago. Across these disparate systems, we show the important perspectives that population genomic data can bring to bear on understanding the history of rapid evolution and diversification.
