Fig. 1

Ancestral-state reconstruction of sexual modes in animals for both (a) “ctenophore-sister” and (b) “sponge-sister” topologies. For each cladogram, the darkened line indicates the sister lineage to the rest of animals. Numbers in parentheses display the number of animals in each lineage used in the analyses. Circles at nodes depict the states assigned by stochastic character mapping while boxes display the maximum parsimony-assigned states. Blue represents gonochorism, red represents hermaphroditism, and yellow represents asexuality. Boxes evenly divided between red and blue colors indicate that gonochorism and hermaphroditism are equally parsimonious explanations of the data. The grey arrows point to the nodes representing the most recent common ancestor of extant animals. Major clades have been collapsed in this figure. The uncollapsed versions are available as Additional file 4: Figures S3, Additional file 5: Figures S4, Additional file 6: Figures S5, Additional file 7: Figures S6
