Basic topology of the evolutionary relationships between birds.
Maximum Likelihood (ML) phylogram reveals the short internodes at the base of Neoaves and highlights certain extreme examples of rate variation across avian lineages. The phylogenetic tree was rooted to crocodilian outgroups (not shown). Branch colors represent major clades supported in this study: land birds (green),…
