Host-use Drives Convergent Evolution in Clownfish and Disentangles the Mystery of an Iconic Adaptive Radiation

Abstract Clownfishes (Amphiprioninae) are a fascinating example of marine radiation. From central Pacific ancestor, they quickly colonized the coral reefs Indo-Pacific and diversified independently on each side Indo-Australian Archipelago. Their association with venomous sea anemones is often thought to be key innovation that enabled clownfish However, this intuition has little empirical or theoretical support given our current knowledge clade. To date, no ecological variable been identified can explain niche partitioning, phenotypic evolution, species co-occurrence, thus, adaptive radiation group. Our synthetic work solves long-standing mystery by testing influence anemone host use divergence. We provide first major revision known clownfish-sea associations in over 30 years, accounting for biologically relevant way. gathered whole-genome data all 28 reconstructed fully supported tree Amphiprioninae. Integrating new into comparative phylogenomic approaches, we demonstrate time, drivers convergent evolution color pattern morphology. During group, clownfishes different regions associate same hosts have evolved phenotypes. Comparative genomics also reveals several genes under positive selection linked specialisation events. results identify as disentangles entire As one most recognizable animals planet an emerging model organism biological sciences, findings bear interpretation dozens prior studies will radically reshape research agendas these iconic organisms.
