Fig. 1From: Genomic bases underlying the adaptive radiation of core landbirdsPhylogenetic relationships of core landbird species used in this study. Phylogenetic relationships among species follow published studies [2, 17, 59, 60, 64,65,66,67,68,69,70,71,72,73] and the Tree of Life Web Project (http://tolweb.org/tree/). The species under gene capture in this study are shown in blue, and the species with gene sequences cited from GenBank are shown in black. The letters (A–J) show the branches under positive selection analyses based on core landbird dataset in this studyBack to article page
