Sphenodontian phylogeny and the impact of model choice in Bayesian morphological clock estimates of divergence times and evolutionary rates

摘要

Summary of models and parameters available for morphological characters that were tested and implemented herein. ACRV, among character rate variation; Asym, asymmetric state frequencies; BI, Bayesian inference; FBD, fossilized birth-death model; GA or ga, Gamma distribution; IGR (independent gamma rates uncorrelated clock model); LN or ln, lognormal distribution MML (SS), marginal model likelihoods (using the stepping-stone procedure); NoSA, no sampling of ancestors; PMF, probability mass function; SA, sampling of ancestors; SFBD, skyline fossilized birth-death model; Sym, symmetric state frequencies; TK02 (Thorne and Kishino continuous autocorrelated clock model). See the “Methods” section for additional details and explanation for different models
