The Evolution and Fossil Record of Palaeognathous Birds (Neornithes: Palaeognathae) [PDF]
Diversity, 2022 The extant diversity of the avian clade Palaeognathae is composed of the iconic flightless ratites (ostriches, rheas, kiwi, emus, and cassowaries), and the volant tinamous of Central and South America.

Evolution of bird sex chromosomes: a cytogenomic approach in Palaeognathae species [PDF]
BMC Ecology and EvolutionBackground Different patterns of sex chromosome differentiation are seen in Palaeognathae birds, a lineage that includes the ratites (Struthioniformes, Rheiformes, Apterygiformes, Casuariiformes, and the sister group Tinamiformes).

Brain shapes of large-bodied, flightless ratites (Aves: Palaeognathae) emerge through distinct developmental allometries [PDF]
Royal Society Open ScienceComparative neuroanatomical studies have long debated the role of development in the evolution of novel and disparate brain morphologies. Historically, these studies have emphasized whether evolutionary shifts along conserved or distinct developmental ...

Microstructural and crystallographic evolution of palaeognath (Aves) eggshells [PDF]
eLife, 2023 The avian palaeognath phylogeny has been recently revised significantly due to the advancement of genome-wide comparative analyses and provides the opportunity to trace the evolution of the microstructure and crystallography of modern dinosaur eggshells.

Internal fossil constraints have more effect on the age estimates of crown Palaeognathae than different phylogenomic data type [PDF]
Frontiers in BioinformaticsPalaeognathae is an ancient bird lineage that includes the volant tinamous and six flightless lineages: ostrich, rhea, cassowary, emu, kiwi (extant) and moa, elephant bird (extinct).

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

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.

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.

Palaeognath birds innovate to solve a novel foraging problem [PDF]
Scientific ReportsThe ability to innovate implies flexible cognition, and is used as a broad metric of intelligence. Innovation in birds has been intensively studied in the larger and more taxonomically diverse Neognathae clade (particularly crows and parrots) and ...
