Tests reveal very little difference in the pattern of speciation in a scenario where taxonomic knowledge is sufficient to make confident estimates of coverage. (a) Speciation rates inferred from the TESS analyses of the data-rich timetree (Harvey et al. 2020) at five different levels of sampling. Darker shading is proportional to greater ρ at the following levels: 100% (darkest blue), 75%, 50%, 25%, and 5% of the total timetree. Note that the overall pattern of speciation is visually similar across all levels. (b) Regression of ρ against the speciation rate hyperprior inferred from TESS analysis.
