  1. The meaning of the rate of transition between states (for example q12, q34) is shown in Figure 2A. Likelihood ratio values for analyses of correlations and tests of contingent evolution and temporal order between a life-history trait (spore size) and sexual system using Discrete. L (U) represents the likelihood of the unconstrained rate estimates, L (C) the likelihood when rates are set to be equal. Likelihood values were tested over a ×2 distribution with one degree of freedom. *P < 0.05. The only highly significant correlation was a gain of dioicy in lineages with small spores (×2= 5.77). A gain of monoicy in lineages with small spores was barely significant (×2= 3.85).
