Presence/absence patterns reconstruct the timing of expansions of dominant CR1 families within five selected avian orders. The number next to the colored circle is the number of CR1 insertions found. Only CR1 families with more than ten CR1 presence/absence patterns (only CR1 insertions ranging between 100 and 600 bp were analyzed) are shown, for the complete number of insertions, see supplementary table 3, Supplementary Material online. Phylogenies adapted from Mitchell et al. (2014), Oliveros et al. (2019), Silva et al. (2017), and Sun et al. (2017).
