Exploring Diversification and Genome Size Evolution in Extant Gymnosperms through Phylogenetic Synthesis

Figure 2

Lineage through time plot for the gymnosperm species. All bootstrap trees, with ultrametric branch lengths from r8s, were pruned to include only the gymnosperm taxa. Each line represents a single ML bootstrap tree. The graph shows the pattern of diversification of the gymnosperm taxa in the tree through time, as the tree grew from a single lineage at the root to the current sampling of 739 species.
