Fig. 3From: Avian phenotypic convergence is subject to low genetic constraints based on genomic evidence(All bird illustrations were reproduced with permission from Lynx Edicions)Derived hypotheses for genomic sequence convergence. Three convergence hypotheses (Hfoot-a, Hfoot-b and Hfoot-c) were derived from the foot-propelled diving convergence hypothesis (Hfoot in Fig. 1) and two (Hrap-a and Hrap-b) from the raptorial convergence hypothesis (Hrap in Fig. 1)Back to article page
