Figure 1From: A phylogeny of the Passerida (Aves: Passeriformes) based on mitochondrial 12S ribosomal RNA gene The maximum-Parsimony tree (strict consensus of 12 trees, L = 911 steps) obtained from the passerine analyses of the 12S ribosomal data. The numbers on the branches are the nodal support data. The proportion of bootstrap replicates in which a given node was recovered is indicated by branch thickness: a thickened branch indicates BP ≥ 90%.Back to article page
