With Next Generation Sequencing (NGS) data being routinely used, phylogenetics is transforming into the era of genomics (i.e., Phylogenomics). These phylogenomic data matrices provide an unprecedented resolution of the tree of life, but inferring a reliable species phylogeny from a large dataset with hundreds of orthologous genes and tens to hundreds of species involves many challenges that create uncertainty with respect to maximum likelihood tree search and gross error with respect to model misspecification. In addition, accurately assessing support and uncertainty across branches is almost as important as building the species phylogeny. The phylogenetic analysis of SARS-CoV-2 stands as a prime example of these challenges; it has been increasingly difficult to keep the phylogeny up to pace with the thousands of new genomes sequenced every day, let alone the proper measurement of the uncertainty. To our knowledge, no concerted effort has been made to simultaneously discuss accurately building the species phylogeny and assessing support across branches in a symposium. In this symposium, we will bring together researchers from around the world who have been developing new approaches to inferring species phylogeny and assessing phylogenetic support in the era of genomics. We aim to discuss the relative merits and drawbacks of these approaches and to highlight common themes.
