Phylogeny of vertebrate species. Three methods were applied to the RAG1 gene from 46 species. Distance method: alignment with ClustalW, (Kimura 2-parameter distance), reconstruction by NJ algorithm. MP: use of same alignment. PAUP* has been used with default parameters. Signature method: 6-letter words – χ2 metric. The tree is inferred by NJ method. The bootstrap coefficients for distance and signature method are indicated.
