Fig. 5. A in A molecular phylogeny of nephilid spiders: Evolutionary history of a model lineage

Fig. 5. A summary nephilid phylogeny based on the Bayesian tree in Fig. 2 with squares at terminals color coded according to biogeographical regions (see right map inset). Branches are also color coded for geography, with the ancestral values inferred using parsimony optimization. Although the tree is not ultrametric (all terminals are in fact contemporary) the roughly estimated main clade ages are labeled according to the scheme A in Fig. 4. The nephilid ancestral age is thus between 40 and 60 million years when the Gondwanan continents were already largely split (see left map inset).
