In recent years, avian systematics has been characterized by a diminished reliance on morphological cladistics of modern taxa, intensive palaeornithogical research stimulated by new discoveries and an inundation by analyses based on DNA sequences. Unfortunately, in contrast to significant insights into basal origins, the broad picture of neornithine phylogeny remains largely unresolved. Morphological studies have emphasized characters of use in palaeontological contexts. Molecular studies…

The present study demonstrates that morphological analysis yields highly congruent results when compared with previous molecular studies; thus, it provides morphological synapomorphies for clades that have been proposed by these molecular analyses.

The phylogeny of charadriiform birds (shorebirds and allies) – reassessing the conflict between morphology and molecules

It is finally noted that recent calibrations of molecular analyses, which indicate an origin of extant charadriiform lineages in the Cretaceous, are based on incorrectly identified fossils.

Phylogenetics of modern shorebirds (Charadriiformes) based on phenotypic evidence: analysis and discussion

A cladistic analysis of 1024 phenotypic characters of Charadriiformes shorebirds found a large set of shortest trees, and some findings challenge previous morphological results, as well as many groupings variably inferred from molecular data.

Metaves, Mirandornithes, Strisores and other novelties – a critical review of the higher‐level phylogeny of neornithine birds

Molecular studies congruently recover some clades that were not recognized by morphologists before and are outlined in the present review, and to ease future discussions the terms Picocoraciae and Aequornithes are introduced.

The evolution of tinamous (Palaeognathae: Tinamidae) in light of molecular and combined analyses

This work presents the first detailed phylogenetic analysis and divergence-date estimation including a significant number of tinamou species, both extant and fossil and estimates that the basal divergence of crown Tinamidae took place between 31 and 40 Mya.

A new phylogenetic analysis of Phytosauria (Archosauria: Pseudosuchia) with the application of continuous and geometric morphometric character coding

This work presents the most taxonomically comprehensive cladistic dataset of phytosaurs to date, based on extensive first-hand study, identification of novel characters and synthesis of previous matrices, which results in an almost twofold increase in phylogenetic information scored per taxon over previous analyses.

Phylogenetic Analysis of Pelecaniformes (Aves) Based on Osteological Data: Implications for Waterbird Phylogeny and Fossil Calibration Studies

Relationships of extant pelecaniforms inferred from morphology are more congruent with molecular phylogenies than previously assumed, though notable conflicts remain.

Phylogenetic interrelationships of living and extinct Tinamidae, volant palaeognathous birds from the New World

Temporal calibration of the resultant phylogeny indicates that such a basal divergence had already taken place in the early Miocene, some 17 million years ago, and the placement of the fossil species within the open-area and the forest-dwelling tinamous is consistent with the palaeoenvironmental conditions inferred from the associated fauna.

The origins of crown group birds: molecules and fossils

  • 2014
It is shown how new sequence‐based phylogenies may shed light on the relationships of fossils with an unexpected character mosaic, and how such fossils can improve the understanding of character evolution in morphologically disparate avian taxa.

Affinities of Palaeospiza bella and the Phylogeny and Biogeography of Mousebirds (Coliiformes)

It is shown that P. bella is a member of the Coliiformes (mousebirds) and represents the latest North American occurrence of a clade with an exclusively African extant distribution and Phylogenetic results imply that a minimum of three mousebird dispersals from Europe to North America occurred during the Early Cenozoic.



Higher-Order Phylogenetics of Modern Aves Based On Comparative Anatomy

P phylogenetic analysis of Mesozoic and modern birds based on the under-utilized wealth of anatomical evidence and drawing primary strength from comparatively complete, neontological specimens, and a preliminary phylogenetic hypothesis based on osteological characters compiled to date are presented.

The origin and early diversification of birds

Numerical cladistic analysis of 73 cranial and postcranial characters has resulted in a highly corroborated hypothesis describing the phylogenetic pattern of early avian evolution. Using “non-avian

A phylogenetic analysis and classification of recent dabbling ducks (Tribe anatini) based on comparative morphology

Cladistic analysis of 157 characters of definitive plumages and soft parts, natal plumages, tracheae, and nontracheal skeletons of 59 Anatini provided a phylogenetic hypothesis of high consistency and resolution and indicated that interspecific interfertility is a poor indicator of relationship.

The deep divergences of neornithine birds: a phylogenetic analysis of morphological characters

A broad array of morphological characters (including both cranial and postcranial characters) are analyzed for an ingroup densely sampling Neornithes, with crown clade outgroups used to polarize these characters.


This work serves as a compendium of anatomical resources upon which a companion phylogenetic analysis of Aves and related Theropoda (Avialae) was based and summarized, to the extent feasible, previously published characters for which inclusion in the present work was judged to be unreliable or lacking sufficient clarity.

A phylogenetic analysis of the Gruiformes (Aves) based on morphological characters, with an emphasis on the rails (Rallidae).

In the species–level analysis of modern Grues, special efforts were made to limit the analytical impacts of homoplasy related to flightlessness in a number of rallid lineages, and relationships among ‘crakes’ remain poorly resolved.

When Molecules and Morphology Clash: A Phylogenetic Analysis of the North American Ambystomatid Salamanders (Caudata: Ambystomatidae)

Extremely conflicting phylogenetic conclusions for the same taxa derived from different data sets are rare. When conflicts do occur, they may result from homoplasy as well as nonindependence of


This analysis provided a case study in the application of phylogenetic nomenclature at the species level and evaluated the relationships among Mesozoic ornithurines including Ichthyornis dispar and the newly identified taxa.

Analyses of mitochondrial DNA nest ratite birds within the Neognathae: supporting a neotenous origin of ratite morphological characters

The findings suggest that the morphological characteristics of the ratite species are secondarily acquired, probably through neoteny and that the ratites are descendants of flying, neognathous ancestors.

Morphological and molecular support for nonmonophyly of the Galloanserae

This paper discusses morphological and molecular data bearing on the earliest evolution of the Neornithes. Phylogenetic analyses of basal neornithine groups frequently result in poorly resolved
