Phylogenetic Analysis of the Four Chordates with Drosophila as an Outgroup
This phylogenetic tree is based on 766 concatenated single copy protein sequences totaling 313,797 amino acid positions with branches proportional to the amount of change. Numerals in bold above the branches indicate the number of gene duplications occurring in each lineage; numerals below indicate branch lengths.
