Ancestral distribution and divergence time estimation of the Araliaceae with global climate over the last 65 million years. (A) Graphical results of ancestral distribution areas at each node of the phylogeny of the Araliaceae obtained by S-DIVA, and divergence times for Araliaceae species were estimated by BEAST. The split between Apiaceae and Araliaceae was set as the calibration point. The map with ancestral ranges was illustrated using MapChart (https://www.mapchart.net/). Colour key indicates possible ancestral ranges; letter combinations indicate a combination of ranges. (B) Climate for the Cenozoic (0–65 Ma). The climatic curve is a stacked deep-sea benthic foraminiferal oxygen-isotope curve and was modified from Zachos et al.51. Q.: Quaternary; Pl.: Pliocene; P.: Pleistocene.
