Phylogeny and diversification of the largest avian radiation.
TLDR
The historical framework suggests multiple waves of passerine dispersal from Australasia into Eurasia, Africa, and the New World, commencing as early as the Eocene, essentially reversing the classical scenario of oscine biogeography.
Whole-genome analyses resolve early branches in the tree of life of modern birds
TLDR
A genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves recovered a highly resolved tree that confirms previously controversial sister or close relationships and identifies the first divergence in Neoaves, two groups the authors named Passerea and Columbea.
Species Concepts and Speciation Analysis
TLDR
A new mechanistic taxonomy of speciation is needed before population genetics, which deals with evolutionary mechanisms, can be properly integrated with speciation theory; that is, the various modes of Speciation should be characterized according to the various forces and genetic mechanisms that underly the evolution of isolating barriers.

  • 7 March 2001
TLDR
The temporal history of the neornithines can be inferred from fossil taxa and the ages of vicariance events, and along with their biogeographical patterns, leads to the conclusion that neORNithines arose in Gondwanaprior to the Cretaceous–Tertiary extinction event.
Historical Biogeography and Patterns of Differentiation within the South American Avifauna: Areas of Endemism
Patterns of diversification within continental biotas: Hierarchical congruence among the areas of endemism of Australian vertebrates
TLDR
Investigation of the extent to which there is hierarchical information about area-relationships contained in the distributions of Australian vertebrates found Distributions of birds and mammals were found to be nearly identical in their hierarchical pattern, and snakes shared the same general pattern of area- relationships.
A palaeobiogeographic model for biotic diversification within Amazonia over the past three million years
TLDR
The history of Psophia, in combination with new geological evidence, provides the strongest direct evidence supporting a role for river dynamics in Amazonian diversification, and the absence of such a roles for glacial climate cycles and refugia.
Discriminating between phylogenetic signal and random noise in DNA sequences
LINEAGE DIVERSIFICATION AND MORPHOLOGICAL EVOLUTION IN A LARGE‐SCALE CONTINENTAL RADIATION: THE NEOTROPICAL OVENBIRDS AND WOODCREEPERS (AVES: FURNARIIDAE)
TLDR
It is found that the Furnariidae exhibit nearly constant rates of lineage accumulation but show evidence of constrained morphological evolution, suggesting that lineage accumulation in tropical continental radiations may not be as limited by ecological opportunities as in temperate or island radiations.
Phylogenetic relationships among modern birds (Neornithes): towards an avian tree of life
Modem perceptions of the inonophyly of avian higher taxa {modern birds, Neomiihes) and their interrelationships are the legacy uf systematic work undertaken in the 19th century. Before Llie…
