Divergence dated UCE dataset with two independent analyses (see methods) shaded (95 % CI) in different colors (although almost entirely overlapping). The inlaid maps are geological reconstructions from [8], reprinted with permission, highlighting the approximate conformation and extent of subaerial land at 10 and 5 MYA. The green indicates land, yellow indicates highland habitat, red triangles represent volcanoes, and the shades of blue represent shallow-deep sea (light–dark blue)
