  • a Distance is the estimated number of replacements per 100 amino acids. Proteins highlighted in bold have a giardial homolog. Factors are sorted from least to greatest Crown Distance.

  • b Inter-kingdom distances only; the animal—animal and fungus—fungus values are excluded

  • c Archaea are represented by Methanococcus jannaschii and Sulfolobus solfataricus
