The phylogenetic relationships of genus Passer (Old World sparrows) have been studied with species covering their complete world living range. Mitochondrial (mt) cyt b genes and pseudogenes have been analyzed, the latter being strikingly abundant in genus Passer compared with other studied songbirds. The significance of these Passer pseudogenes is presently unclear. The mechanisms by which mt cyt b genes become pseudogenes after nuclear translocation are discussed together with their mode of… 
A revised multilocus phylogeny of Old World sparrows (Aves: Passeridae)
An updated phylogeny of Passeridae covering about two third of the family’s species richness is provided, and contrary to previous classifications, bush sparrows and rock sp Sparrows were not sister taxa, and therefore their classification in separate genera Gymnoris and Petronia is justified.
Low number of mitochondrial pseudogenes in the chicken (Gallus gallus) nuclear genome: implications for molecular inference of population history and phylogenetics
The number of Numts in chicken is low compared to those in human and plant genomes, and is within the range found for most sequenced eukaryotic genomes.
A phylogenetic supertree of oscine passerine birds (Aves: Passeri)
An estimate is presented of the phylogenetic relationships of 1723 extant and one extinct species of oscine passerine birds (Aves: Passeri) — more than 37% of the total — and a heuristic approach is preferred where the adequacy of taxon sampling and molecular method of each source tree is judged instead of using matrices and automated tree‐building programs.
Molecular Phylogeny and Phylogeography of Reed Warblers and Allies (Aves: Acrocephalidae)
DNA sequences from eight mitochondrial and nuclear loci as well as genomic ISSR fingerprinting were implemented to reconstruct the phylogenetic relationships among 35 species of reed warblers, and a molecular clock analysis confirmed the hypothesis of the rapid radiation of the family from middle Miocene (12.5 MYA).
Non‐monophyly of the avian genus Seicercus (Aves: Sylviidae) revealed by mitochondrial DNA
The results suggest that both Seicercus and Phylloscopus are paraphyletic, and the importance of dense sampling at the specific and infraspecific levels in intrageneric phylogenetic studies is underscore.
Evolution within the nuthatches (Sittidae: Aves, Passeriformes): molecular phylogeny, biogeography, and ecological perspectives
A biogeographical analysis supports the hypothesis of Asia being the center of diversification for nuthatches, with several independent dispersal events to North America.
Rhodopechys obsoleta (desert finch): a pale ancestor of greenfinches (Carduelis spp.) according to molecular phylogeny
The evolutionary history of three out of four birds traditionally classified into the genus Rhodopechys birds has been studied by comparing their mitochondrial cytochrome b DNA sequence with that of


Rapid Radiation of Canaries (Genus Serinus)
Mitochondrial cytochrome b DNA from 20 out of 37 extant canaries (genus Serinus) has been sequenced from living specimens photographed around the world and suggests a remarkably rapid radiation when compared to other passerine (songbird) genera radiations.
Mitochondrial resolution of a deep branch in the genealogical tree for perching birds
The mitochondrial tree shows broad concordance with that based on hybridization of nuclear DNA; however, parsimony and maximum likelihood methods suggest a close kinship between thrushes and Australian babblers, in agreement with the traditional morphological classification.
Phylogeny and rapid Northern and Southern Hemisphere speciation of goldfinches during the Miocene and Pliocene Epochs
Molecular comparison of most extant songbird species belonging to the genus Carduelis does not support the assertion that Pleistocene glaciations played a crucial role in the origin of extant diversity and distribution of Northern Hemisphere vertebrates, and a tentative classification for genuscarduelis species is suggested.
The mtDNA sequence of the ostrich and the divergence between paleognathous and neognathous birds.
Molecular dating of the divergence between the ostrich and the chicken indicates that these two avian lineages separated 80-90 MYA, and Phylogenetic analysis of complete cytochrome b genes of six avian orders showed that Passeriformes represent the earliest divergence among recent birds, contradicting the commonly accepted notion of a basal position of the Palaeognathae among recent Birds.
Insertions and duplications of mtDNA in the nuclear genomes of Old World monkeys and hominoids
Two divergent cytochrome b nuclear pseudogenes from orangutan cellular DNA are amplified and sequenced using oligonucleotide primers designed to match conserved regions of mammalian mitochondrial DNA (mtDNA) to find the source of DNA contamination of 'ancient' and forensic DNA.
Phylogeography of crossbills, bullfinches, grosbeaks, and rosefinches
Phylogenetic analyses consistently gave the same groups of finches and the calculated divergence times suggest that speciation of the studied species occurred between 14 and 3 million years ago (Miocene-Pliocene), appearing before the Passer, Carduelis, and Serinus genera.
Rates of nuclear DNA evolution in pheasant-like birds: evidence from restriction maps.
To examine the tempo of genomic evolution in birds, 161 restriction sites in the nuclear DNA of seven species of birds belonging to the pheasant superfamily Phasianoidea were mapped and the mean rate of DNA divergence was estimated to be 0.34-0.40% per million years.

A direct comparison of a fragment of the mitochondrial gene coding for Cytochrome b and its assumed nuclear pseudogene in a phylogenetic context is presented, showing mitochondrial third position transitions are the fastest accumulating substitutions, here indicated to be at least up to 39 times faster than corresponding positions in the supposednuclear pseudogene.
Molecular divergence and phylogeny: rates and patterns of cytochrome b evolution in cranes.
Analyses of complete cytochrome b sequences from all species of cranes reveal aspects of sequence evolution in the early stages of divergence, with Silent, third-position pyrimidine transitions being the dominant substitution type.

Ramphocelus tanagers are distributed throughout the Neotropical lowlands. In this paper, mitochondrial DNA (mtDNA) sequence data from cytochrome b and ND2 genes are used to estimate relationships
