Fig. 4From: Phylogenomics of a rapid radiation: is chromosomal evolution linked to increased diversification in north american spiny lizards (Genus Sceloporus)?Gene tree congruence in the Sceloporus rapid radiation. The majority of species groups in Sceloporus are supported by fewer than 50 % of the gene trees (a), and there is a positive correlation between gene tree congruence and the duration of a branch (b)Back to article page
