  1. Test for positive selection using the M1a (neutral) and M2a (positive) models, and a maximum of 60 Rag1 sequences for each vertebrate lineage (see Methods for further explanations). "d N /d S " indicates the substitution rate ratio averaged across all sites and lineages. "PSS" indicates the positively selected sites (calculated as in [47]). We indicate the position of the amino acid under positive selection (based on the within group alignment used for this analysis) and the corresponding amino acid. * indicates the statistically significant p-values (<0.05) in the Chi-square test.
