Universal and Eukaryote Phylogenetic Trees. Structural similarites for 900 sites that can be unambiguously aligned in a data set of more than 800 eukaryotes and 100 prokaryotes were computed and converted to evolutionary distances using the Kimura two parameter model. The Neighbor-Joining method was used to infer the unrooted universal phylogeny shown in A. A similar computation was used to infer an unrooted phylogeny in B for diverse eukaryotes but this analysis is based upon comparisons of 1200 positions that can be unambiguously aligned. Evolutionary distances in these trees are proportional to length of line segments separating taxa.
Oh my goodness! Unless you are a Tree of Life developer,
you really shouldn't be here. This page is part of our beta test site, where we
develop new features for the ToL, often messing up a thing or two in the
process. Please visit the official version of this page, which is available
here.
