In b, d, and e, horizontal dashed lines and the right-hand y-axis mark statistical support cutoffs for rate shifts, with 2 ≤ Bayes factors (BF) < 6 considered to be low support, 6 ≤ BF < 10 considered to be moderate support and ≥10 considered to be high support. The rate shifts observed in a, c, and e over the last 10 million years are likely an artifact of the CoMET model (see Supplementary Information for further discussion). a, Posterior mean (blue line) and 95% credible interval (blue shading) for acanthomorph lineage origination (that is speciation) rates through time. b, Bayes factor (BF) support for a shift in lineage origination rate at every 1 Myr time period. c, Posterior mean (pink line) and 95% credible interval (pink shading) for acanthomorph lineage extinction rates through time. d, Bayesian support (in BF) for a shift in extinction rate at every 1 Myr time period. e, Posterior mean (violet line) and 95% credible interval (violet shading) for acanthomorph net-diversification (origination minus extinction) rates through time. Though this plot suggests that there is a small shift in net-diversification rate ~50 Mya, there is no statistical support for such a shift (see b and d). f, There is no statistical support (in BF) for a mass extinction event in Acanthomorpha at any 1 Myr time period.
