Figure 3From: Insights into the evolution of Darwin’s finches from comparative analysis of the Geospiza magnirostris genome sequencePhylogeny of seven amniotic species. Branch lengths are proportional to d S ; the degree of constraint (d N /d S ) for each terminal lineage is also indicated (values shown in red). Evolutionary rates (d S and d N /d S ) are median values deriving from 1,452 alignments of simple one-to-one orthologues present in each species.Back to article page
