This event is part of our ongoing Thursday Seminar Series.

About: Explaining the origins of the extraordinary morphological diversity among life forms is a central goal in evolutionary biology. Despite great progress in unraveling the rules of morphological evolution, our understanding of the spectacular diversity of fishes is hindered by the limited inclusion of fossils, paleoclimatic, and genomic data in macroevolutionary analyses. My presentation shows how leveraging museum collections, in combination with macroevolutionary approaches that include data from fossil and extant species, can shed new light on diversification processes operating across the Fish Tree of Life. Topics covered include the effects of paleoclimatic events on morphological and lineage diversification, as well as the evolution of morphological innovations shaping the diversity of fishes through deep time. I will end the presentation by discussing future directions of my research program, such as the use of phylogenetic genotype-to-phenotype mapping approaches integrating chromosome-level genomes.
