Comparison between the two gene trees Strict consensus trees from parsimony analyses of the RAG-1 and the myoglobin intron II data sets, respectively. The RAG-1 tree is calculated from the 72 most parsimonious trees (length 483 steps, CI 0.70, RI 0.60), and the myoglobin tree is calculated from the 30 most parsimonious trees (length 627 steps, CI 0.73, RI 0.62).
