Fig. 2 in Phylogenomics and Fossil Data Inform the Systematics and Geographic Range Evolution of a Diverse Neotropical Ant Lineage

Fig. 2. MCMCTree time-scaled phylogeny (RAxML topology pruned to one tip per species) with historical biogeographic range inferences from the four-node fossil-constrained BioGeoBEARS analysis mapped onto nodes. An asterisk (*) indicates the location of a fossil node calibration.The light purple shading spans the proposed start and end dates (35–32 Mya) of the GAARlandia land bridge linking South America to the Antilles.The light gold shading spans the potential early start date and the complete closure date of the Panamanian land bridge (10–3.5 Mya).Transitions with boxes outlined in red denote differences from the historical geographic range inference without fossil constraints (Supp Fig. S7 [online only]). A, Antilles; C, Central America; S, South America.
