GC content distribution in G. magnirostris. Panel (A) shows the variation of GC content in 3Kb windows along scaffold 10304, the largest scaffold in the assembly. Panel (B) shows the third codon position GC content (GC3) and the equilibrium GC3 (GC3*) content in different vertebrate lineages. The predicted increase in GC content along the Darwin's finch lineage is consistent with the maintenance of GC-rich isochores.
