Digest: More than just a pretty fin: The evolution of sexual ornaments in killifish.

Evolution; international journal of organic evolution - 1 Jan 2022

Abstract excerpt

What conditions favor the evolution of elaborate sexual ornaments? In freshwater killifishes, Sowersby et al. found that larger sexual ornaments were negatively associated with locomotive performance. Although selection clearly favored large ornamental fins in environments with fewer predators, there was no clear association between large ornamental fins and differences in life-history strategy. This finding...
