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 "Ecological divergence plays an important role in strong but complex reproductive isolation in campions (Silene) [4]." Highlight by Sophie Karrenberg.
