Fig. 4 Biogeographic history of the orchid family. (a) Ancestral areas at nodes inferred on the 10 posterior probability species trees as estimated by a DEC model (see the Materials and Methods section) and summarised to the five orchid subfamilies (Inset: A summary of the outgroup sampling considered in our study (the MRCA of orchids is indicated with a black star)). (b) A palaeoclimatic and tectonic plate reconstruction at 90–80 Ma from Burgener et al. (2023) showing the possible ancestral range of the orchid MRCA as estimated by Givnish et al. (2016) and this study. A detailed account of the first and second most likely ancestral areas estimated to the tribe level is provided on Supporting Information Table S5 (complete results including annotated trees with the most likely ancestral area at nodes and alternative ancestral areas, likelihoods and probabilities are available at 10.6084/m9.figshare.22245940).
