Abstract
Understanding the evolutionary history of species is at the core of
molecular evolution and is done using several inference methods. The
critical issue is to quantify the uncertainty of the inference. The
posterior probabilities in Bayesian phylogenetic inference and the
bootstrap values in frequentist approaches measure the variability of the
estimates due to the sampling of sites from genes and the sampling of genes
from genomes. However, they do not measure the uncertainty due to taxon
sampling. Taxa that experienced molecular homoplasy, recent selection, a
spur of evolution and so forth may disrupt the inference and cause
incongruences in the estimated phylogeny. We define a Taxon Influence Index
to assess the influence of each taxon on the phylogeny. We found that
although most taxa have a weak influence on the phylogeny, a small fraction
of influential taxa strongly alter it, even in clades only loosely related
to them. We conclude that highly influential taxa should be given special
attention and sampling them more thoroughly can lead to more dependable
phylogenies.
