Studying the evolution of species is usually envisaged from either a population perspective or using a phylogenetic context and both approaches have brought essential elements to understand the process of speciation. Despite these achievements, unifying these two fields is seen as one of the remaining challenges in evolutionary biology. In particular, providing a bridge between the evolutionary processes stemming from variation at the intraspecific level with interspecific variation is an extremely difficult task. These two organizational levels have thus been largely decoupled methodologically and conceptually.Here, we will combine theoretical developments with empirical genomic data to tackle this specific task and bridge micro- and macro-evolutionary processes. We first propose a novel approach that uses hierarchical Bayesian modeling to extend current macro-evolutionary models and allow the incorporation of trait variance in the estimates of evolutionary rates. The development of new methodologies is a key step to reach our goal. The availability of new empirical data sets to assess the effects of phenotypic variance on evolutionary processes at the micro- and macro-evolutionary scales is also essential. We will use a newly described adaptive radiation to study the evolution of this extraordinary species and phenotypic diversification both from a comparative perspective and from population level studies.We propose an integrative study of the clownfish adaptive radiation with the objective to ultimately enhance our knowledge of the processes determining species diversity by combining computationally innovative and challenging approaches with high-throughput genomic data. The goal is to better characterize the link between macro-evolutionary patterns and the micro-evolutionary mechanisms. This will advance our empirical and theoretical knowledge of a phenomenon that is thought to explain the diversity of life and the processes behind the origin of species.
