^aBayes factors were estimated by comparing marginal likelihoods of the different evolutionary models (Tracer v1.5.0). The H₀ (null) models are in the row while the H₁ (alternative) models are in the columns. Evidence against H₀ was assessed in the following way: 0–6 indicates positive evidence for H₁, and X>6 indicates strong evidence. The relaxed exponential, relaxed logistic, and strict logistic were not included, because the ESS was X<150. The BSP model fitted the data set better than constant, exponential, and logistic.
