Research reveals phylogenetic relationships and biogeographic origins of Euphorbieae, highlighting evolutionary drivers.

This research aims to resolve the species-level phylogeny and biogeographic history of the Euphorbieae tribe within the Euphorbiaceae family.
Reconstructed phylogenetic relationships using plastome and nuclear ribosomal DNA data sets.
Analyzed 34 species from three subtribes across five genera of Euphorbieae.
Estimated divergence times and inferred ancestral areas through biogeographic analyses.
Supported the monophyly of Euphorbieae with clarified sister relationships among subtribes.
Established the crown age of Euphorbieae at approximately 62.11 million years ago in the early Paleocene.
Identified an African origin with subsequent dispersal events to Australasia, Asia, and the Neotropics.

Atolwa et al. (2026) studied this question.
