## Figure 2.
Our current best hypothesis for the phylogenetic relationships of all . Depicted is result of the maximum likelihood bootstrap analysis. Numbers on branches
show, respectively, the support values for 100 bootstrap repeats in the ML analysis
in percent, the posterior probabilities from the Bayesian inference analysis (blue),
and the support values for 2000 jackknife repeats in a weighted maximum parsimony
analysis in percent. * Weighted maximum parsimony analysis favors a position of Caenorhabditis in culture and convergent evolution of hermaphroditismC. sp. 15 as the sister species of the Elegans group with 60% support. ** Bayesian inference favors C. sp. 20 to form the sister species of the Angaria and Drosophilae groups with a clade credibility value of 96, the lowest in this analysis. Three species
(in red) reproduce as self-fertilizing hermaphrodites with rare males, whereas all
other species (in blue) are gonochoristic with females and males at approximately
equal proportions. Hermaphroditism evolved convergently in all three lineages.
