Building the avian tree of life using a large-scale, sparse supermatrix.

Birds are the most diverse tetrapod class, with about 10,000 extant species that represent a remarkable evolutionary radiation in which most taxa arose during a short period of time. There has been a tremendous increase in the amount of molecular data available from birds, and more than two-thirds
Resolving the root of the avian mitogenomic tree by breaking up long branches.

Incomplete taxon sampling has been a major problem in resolving the early divergences in birds. Five new mitochondrial genomes are reported here (brush-turkey, lyrebird, suboscine flycatcher, turkey vulture, and a gull) and three break up long branches that tended to attract the distant reptilian
African endemics span the tree of songbirds (Passeri): molecular systematics of several evolutionary 'enigmas'.

The deep divergence between the African endemic passerines Picathartidae (rockfowl Picathartes and rockjumpers Chaetops, four species) and the Passerida (ca. 3500 species) suggests an older history of oscines on the African continent than has previously been assumed. In order to determine whether
An unbiased molecular approach using 3'UTRs resolves the avian family-level tree of life

Presumably, due to a rapid early diversification, major parts of the higher-level phylogeny of birds are still resolved controversially in different analyses or are considered unresolvable. To address this problem, we produced an avian tree of life, which includes molecular sequences of one or
The African warbler genus Hyliota as a lost lineage in the Oscine songbird tree: molecular support for an African origin of the Passerida.

The African genus Hyliota includes three or four species of warbler-like birds of uncertain phylogenetic affinities, as it has historically been placed in different avian families that are now known to represent unrelated lineages: Malaconotidae (bush-shrikes), Platysteiridae (batises and
A Paleogene origin for crown passerines and the diversification of the Oscines in the New World.

In this study, we present a detailed family-level phylogenetic hypothesis for the largest avian order (Aves: Passeriformes) and an unmatched multi-calibrated, relaxed clock inference for the diversification of crown passerines. Extended taxon sampling allowed the recovery of many challenging clades

Recent developments in phylogenetic methods and data acquisition have allowed for the construction of large and comprehensive phylogenetic relationships. Published phylogenies represent an enormous resource that not only facilitates the resolution of questions related to comparative biology, but

The order Passeriformes ("perching birds") comprises extant species diversity comparable to that of living mammals. For over a decade, a single phylogenetic hypothesis based on DNA-DNA hybridization has provided the primary framework for numerous comparative analyses of passerine ecological and

The Timaliidae, a diverse family of oscine passerine birds, has long been a subject of debate regarding its phylogeny. The mitochondrial cytochrome c oxidase subunit I (COI) gene has been used as a powerful marker for identification and phylogenetic studies of animal species. In the present study,

The Eurylaimides is one of the few passerine groups with a pantropical distribution. In this study, we generated a multi-calibrated tree with 83% of eurylaimid species diversity based on 30 molecular loci. Particular attention was given to the monotypic Sapayoidae to reconstruct the biogeography of
Resolving phylogenetic relationships within Passeriformes based on mitochondrial genes and inferring the evolution of their mitogenomes in terms of duplications.

Mitochondrial genes are placed on one molecule, which implies that they should carry consistent phylogenetic information. Following this advantage, we present a well-supported phylogeny based on mitochondrial genomes from almost 300 representatives of Passeriformes, the most numerous and

The superb fairy-wren, Malurus cyaneus, is one of the most iconic Australian passerine species. This species belongs to an endemic Australasian clade, Meliphagides, which diversified early in the evolution of the oscine passerines. Today, the oscine passerines comprise almost half of all avian

The origin of vocal learning in animals has long been the subject of debate, but progress has been limited by uncertainty regarding the distribution of learning mechanisms across the tree of life, even for model systems such as birdsong. In particular, the importance of learning is well known in

The New World sparrows (Emberizidae) are among the best known of songbird groups and have long-been recognized as one of the prominent components of the New World nine-primaried oscine assemblage. Despite receiving much attention from taxonomists over the years, and only recently using molecular

This paper documents the phylogenetic utility of ZENK at the avian intra-ordinal level using hummingbirds, swifts, and passerines as case studies. ZENK sequences (1.7 kb) were used to reconstruct separate gene trees containing the major lineages of each group, and the three trees were examined for
