Genomic data are important for understanding the origin and evolution of traits. Under the
context of rapidly developing of sequencing technologies and more widely available …

The karyotype of most birds has remained considerably stable during more than 100 million
years' evolution, except for some groups, such as parrots. The evolutionary processes and …

How much do we really know about bird genomes? Like other eukaryotic genomes, the
genomes of birds contain repetitive DNA—tandem repeats, transposable elements, and …

Telomeres, the short DNA sequences that protect chromosome ends, are an ancient
molecular structure, which is highly conserved across most eukaryotes. Species differ in …

Population genetics is the study of genetic variation within populations and how allele
frequencies change over space and time. This field largely focuses on the five fundamental …

Current generation high-throughput sequencing technology has facilitated the generation of
more genomic-scale data than ever before, thus greatly improving our understanding of …

Chromosome rearrangements are often implicated with genomic divergence and are
proposed to be associated with species evolution. Rearrangements alter the genomic …

Abstract Doradinae (Siluriformes: Doradidae) is the most species-rich subfamily among
thorny catfishes, encompassing over 77 valid species, found mainly in Amazon and Platina …

A traditional aim of avian taxonomists and systematists was to establish a reliable
phylogenetic framework, the avian tree of life. Until 50 years ago, the only way to establish …

 Abstract Birds are one of the most diverse groups among terrestrial vertebrates. They
evolved from theropod dinosaurs, are closely related to the sauropsid group and separated …
