  • Novelty of Approach

     

    -Uses codon aversion in orthologs to recover phylogenies

    -Compares strength of phylogenetic signal in different codons

    -Analyzes 17,717 orthologs across 72 tetrapods

     

  • Results

     

    -Phylogenetic signal of stop codons is most congruent with the Open Tree of Life

    -Phylogenetic signal not due to single-instance codons

    -Codon usage is largely conserved throughout tetrapods.

     

  • Implications

     

    -Novel phylogenetic character state

    -Might be used in maximum likelihood or alignment-free methods

    -Some codon usages are more phylogenetically conserved than others

  • Stop Codon Clades Recovered Using Fewer Genes
