Persistent conflict in palaeognath phylogeny revealed by quartet-based and ML analyses [PDF]
Frontiers in ZoologyBackground The evolutionary relationships among palaeognath birds remain contentious despite extensive phylogenomic analyses. While the ostrich is consistently identified as the earliest diverging lineage, the relationships among non-ostrich palaeognaths

The Comparative and Developmental Genomics of Flightlessness in Birds (Palaeognathae)
, 2020 Convergent evolution results in shared, analogous phenotypes among evolutionarily distinct lineages. Thus, vertebrates have evolved flight independently in pterosaurs, bats, and birds, an event that requires the co-occurrence of many physiological and ...

ZIC3 shapes digit morphogenesis in avian [PDF]
Poultry ScienceThrough the evolutionary diversification of birds, a variety of digit morphologies have evolved as adaptations to diverse environments, with the regression of the anterior digits being a remarkable phenomenon.

A Derived Morphology of the Quadrate May Support a Previously Unrecognized Major Higher-Level Clade of Neoavian Birds. [PDF]
J MorpholThe avian quadrate plays a critical role in cranial kinesis, but few comparative studies exist of its morphological variation across higher‐level taxa. In this study, the occurrence of a markedly concave articular facet of the condylus medialis is surveyed across neornithine birds.

New view on the organization and evolution of Palaeognathae mitogenomes poses the question on the ancestral gene rearrangement in Aves [PDF]
BMC Genomics, 2020 Background Bird mitogenomes differ from other vertebrates in gene rearrangement. The most common avian gene order, identified first in Gallus gallus, is considered ancestral for all Aves.

Metabolic rate, sleep duration, and body temperature in evolution of mammals and birds: the influence of geological time of principal groups divergence [PDF]
ZooKeys, 2023 This study contains an analysis of basal metabolic rate (BMR) in 1817 endothermic species. The aim was to establish how metabolic scaling varies between the main groups of endotherms during evolution.

Data from: Whole-genome analyses resolve the phylogeny of flightless birds (Palaeognathae) in the presence of an empirical anomaly zone [PDF]
Systematic Biology, 2019 Palaeognathae represent one of the two basal lineages in modern birds, and comprise the volant (flighted) tinamous and the flightless ratites. Resolving palaeognath phylogenetic relationships has historically proved difficult, and short internal branches

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology. [PDF]
J AnatThe preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Hindlimb morphology of Palaeotis suggests palaeognathous affinities of the Geranoididae and other “crane-like” birds from the Eocene of the Northern Hemisphere [PDF]
Acta Palaeontologica Polonica, 2019 The early/middle Eocene Palaeotis weigelti is a flightless bird, which occurs in the fossil localities Messel and Geiseltal (Germany). The species is assigned to the Palaeognathae and some authors considered it to be a stem group representative of the ...
