This archive contains single gene sequence alignments for 657 "1-to-1 orthologs" used go generate a species phylogeny for the study. Each directory contains the single-gene sequence alignment in multi-FASTA format, and the results of a maximum likelihood search in RAXML. Nucleotide sequences were aligned with MAFFT and trimmed with trimal to remove columns represented by fewer than 5 taxa. Phylogenies were reconstructed with the GTRGAMMA substitution model and nodal support was evaluated with 200 "fast bootstrap" replicates.
