A Bayesian tree of 39 eukaryotes using 20 genes. The topology was estimated from the Euk-S39G20 dataset by Phylobayes using CAT model. The five eukaryotic supergroups are colored as following; red, Amoebozoa; black, Opisthokonta; green, Archaeplastida; blue, SAR; and brown, Excavata. The branch leading to Giardia is shown as a quarter of the original length. Posterior Probability (PP) support values from Bayesian analyses using Euk-S39G20 (first number) and Euk-S39G25 (second number) are shown for each nodes. Black dots indicate 100% PP support from both 20- and 25-gene analyses.
