Extended Data Fig. 1. TimeTree phylogeny for the focal species studied here.

TimeTree⁸³ phylogeny for the species studied here. The phylogeny at the top provides estimates of node ages that are assessed across multiple studies that have dated the splits among clades. Asterisks denote cases where a substitute species was selected by TimeTree to be used as data on the target species was unavailable. The substituted species are not the same as those analysed in our study. Substituted species are: Amaranthus hybridus (A. tuberculatus); Eucalyptus erythrocorys (E. albens); Quercus rubra (Quercus petraea). A number of species are missing that were analysed, but congeneric representatives are shown (missing species: Helianthus petiolaris, E. magnificata, E. sideroxylon, Pinus contorta, Picea glauca x engelmannii).
