Accurate inference of species relationships is crucial to address fundamental questions in evolutionary biology. Empiricists have greatly benefitted from the continual ease of generating sequence data for phylogenetic inference and can now employ genome-scale datasets to infer the evolutionary history of clades across the tree of life. However, the availability of large phylogenomic datasets are not a panacea for all phylogenetic issues and these large datasets often present new challenges. In particular, individual genetic markers can have discordant phylogenetic histories due to processes such as incomplete lineage sorting, introgression and selection, potentially clouding the inference of organismal relationships. Most contemporary species tree estimation methods aim to model observed incongruence using the multi-species coalescent but these approaches often assume incomplete lineage sorting as the single source of discord and are computationally exhaustive or rely on the precision of individual gene trees. The development of novel approaches to account for sources of phylogenetic incongruence therefore remains a thriving area of research. Given the vigorous state of the field, it is thus timely to discuss recent advances and remaining challenges of species tree estimation in a symposium where we invite both theoreticians and empiricists.
