The Evolution Highlights [1] series showcases some of the interesting and varied papers published within the last few years in Evolution [2]. The goal of these Evolution Highlights is to let our readers learn more about how the highlighted study came into existence and to invite the authors to share stories and tips from the perspective of a recently published author. We welcome nominations and self-nominations [3] for this series.

Here we highlight "In love and war: The morphometric and phylogenetic basis of ornamentation, and the evolution of male display behavior, in the livebearer genus Poecilia [4]." Highlight by Daniel Goldberg.
