Extended Data Fig. 6: Patterns of diversification-rate-variation in chloroplast time-calibrated phylogenies inferred with smoothing values that differ from the optimum.

Extended Data Fig. 6

The coloured trees, posterior probabilities, and coloured arrows are indicated according to the same conventions as Extended Data Fig. 4. a) A model with no discrete rate shifts has a posterior probability of 0.54. Two alternative patterns of diversification-rate-variation, where there are rate increases near the origin of the diverse South American clade, have posterior probabilities of 0.34 and 0.058 respectively. b) A single rate shift near the origin of the diverse South American clade has a posterior probability of 0.51. An alternative pattern of diversification-rate-variation, where there is a rate increase on immediately ancestral branch, has a posterior probability of 0.088. c) A single rate shift at the origin of the diverse South American clade has a posterior probability of 0.81. An alternative pattern of diversification-rate-variation, where there is a rate increase on an immediately ancestral branch, has a posterior probability of 0.11.
