Substitution rates. Average distance of orthologous sequences from (1) C. intestinalis, (2) one vertebrate, and (3) B. floridae. a - correspond to the distance between C. intestinalis and the common ancestor with vertebrate, and b is the distance between vertebrate and the common ancestor with C. intestinalis. See Figure  1S, in supplementary materials.
