Fig. 6 — The calibrated time of duplication of cryptochromes (CRYs) for the evolution and diversification of ferns. The phylogenetic tree and the time of species diversification were generated by TimeTree (http://www.timetree.org/; for more detail see Supporting Information Tables S8, S9). Four duplication events are labeled with orange, brown, purple and cyan boxes. The width of the boxes represents the estimated time‐frame for gene duplication, and the length of the boxes represents the coverage of lineages. The estimated times of gene duplication were 386–418 Ma (orange), 373.9–404.9 Ma (brown), 196.9–212.9 Ma (purple) and 151.8–164.4 Ma (cyan). Geological timescale abbreviations: Ng, Neogene; Pg, Paleogene; MIS, Mississippian; S, Silurian; O, Ordovician; C, Cambrian; CRI, Cryogenian; STA, Statherian.
