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).

The selfish preen: absence of allopreening in Palaeognathae and its socio-cognitive implications [PDF]
Animal Cognition, 2023 Preening behaviours are widespread in extant birds. While most birds appear to autopreen (self-directed preening), allopreening (preening directed at conspecifics) seems to have emerged only in certain species, but across many families.

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 ...

Broad-scale recombination pattern in the primitive bird Rhea americana (Ratites, Palaeognathae). [PDF]
PLoS ONE, 2017 Birds have genomic and chromosomal features that make them an attractive group to analyze the evolution of recombination rate and the distribution of crossing over.

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).

The phylogenetic significance of the morphology of the syrinx, hyoid and larynx, of the southern cassowary, Casuarius casuarius (Aves, Palaeognathae) [PDF]
BMC Evolutionary Biology, 2019 Background Palaeognathae is a basal clade within Aves and include the large and flightless ratites and the smaller, volant tinamous. Although much research has been conducted on various aspects of palaeognath morphology, ecology, and evolutionary history,

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.

Phylogeny and sex chromosome evolution of palaeognathae
Journal of Genetics and Genomics, 2022 Many paleognaths (ratites and tinamous) have a pair of homomorphic ZW sex chromosomes in contrast to the highly differentiated sex chromosomes of most other birds. To understand the evolutionary causes for the different tempos of sex chromosome evolution,

The Length Polymorphism of the 9th Intron in the Avian CHD1 Gene Allows Sex Determination in Some Species of Palaeognathae. [PDF]
Genes (Basel), 2022 In palaeognathous birds, several PCR-based methods and a range of genes and unknown genomic regions have been studied for the determination of sex. Many of these methods have proven to be unreliable, complex, expensive, and time-consuming.
