Fig. 1: The relationship between species age and range size.
From: Evolutionary age correlates with range size across plants and animals
Relationship between species age (median age across 100 phylogenetic trees) and range size, with the solid line representing the predicted mean (model fit) and the shaded area representing the 95% confidence interval of the predictions, for A all species, and (B–H) separated for the seven broad taxonomic groups: (B) amphibians, C reef fishes, D birds, E reptiles, F)palms, G terrestrial mammals, and H) marine mammals. Geological periods are denoted as Ng Neogene, Pg Paleogene, K Cretaceous, and J Jurassic. Note that both axes are log10-transformed, consistent with the transformation used in the analyses. n number of species; Myr million years. These results were robust to outliers and different approaches to calculating species age (Supplementary Fig. 2–3, and Supplementary Table 3–4). Source data is provided as a Source Data file.
