Fig. 4

The relationship between node depths (relative to the base node) for species trees that were estimated using the multispecies coalescent (MSC) a concatenated alignment (inferred by maximum likelihood). In a the bivariate relationship between the inferred depths is shown, and in b the difference between the height inferred by concatenation and the MSC is shown, as a proportion of the depth inferred by the MSC [(concatentation – MSC) / MSC]
