From: A Bayesian framework to estimate diversification rates and their variation through time and space
Clade-specific analysis of the radiation of the genus Lupinus. Clades in the phylogenetic tree are labeled according to their distribution: I - Old World (Europe and North Africa), II - Eastern New World, III - Western North America and Central America, IV - Andean. Colors indicate the mean rates of diversification, with posterior rate estimates (relative densities) shown in the plot on the left (I - 0.20, II+III - 0.89, IV - 2.56). Note that the best model identified using Bayes Factors is a three-rate model in which clades II and III evolve at the same rate.
