| Summary: | Phylogenomics has the power to uncover complex phylogenetic scenarios across the genome. In most cases, no single topology is reflected across the entire genome as the phylogenetic signal differs among genomic regions due to processes, such as introgression and incomplete lineage sorting. Baleen whales are among the largest vertebrates on Earth with a high dispersal potential in a relatively unrestricted habitat, the oceans. The fin whale (Balaenoptera physalus) is one of the most enigmatic baleen whale species, currently divided into four subspecies. It has been a matter of debate whether phylogeographic patterns explain taxonomic variation in fin whales. Here we present a chromosome-level whole genome analysis of the phylogenetic relationships among fin whales from multiple ocean basins. First, we estimated concatenated and consensus phylogenies for both the mitochondrial and nuclear genomes. The consensus phylogenies based upon the autosomal genome uncovered monophyletic clades associated with each ocean ... : # Phylogenomics and pervasive genome-wide phylogenetic discordance among fin whales (Balaenoptera physalus) [https://doi.org/10.5061/dryad.v6wwpzh24](https://doi.org/10.5061/dryad.v6wwpzh24) ## Description of the data and file structure # DATA OVERVIEW 1. **Alignments** File: final_phylogeny_auto_filt_snps.min4.phy.gz Description: Whole autosomal genome alignment containing a total of monomorphic and SNP sites.
