Open AccessRapid gene content turnover on the germline-restricted chromosome in songbirds
The germline-restricted chromosome (GRC) of songbirds represents a taxonomically widespread example of programmed DNA elimination. Despite its apparent indispensability, we still know very little about the GRC...

Open AccessGenomic architecture of migration timing in a long-distance migratory songbird
The impact of climate change on spring phenology poses risks to migratory birds, as migration timing is controlled predominantly by endogenous mechanisms. Despite recent advances in our understanding of the un...

Open AccessThe genomic basis of the plant island syndrome in Darwin’s giant daisies
The repeated, rapid and often pronounced patterns of evolutionary divergence observed in insular plants, or the ‘plant island syndrome’, include changes in leaf phenotypes, growth, as well as the acquisition o...

Open AccessRecurrent chromosome reshuffling and the evolution of neo-sex chromosomes in parrots
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 underlying genetic mechanism ...

Dense sampling of bird diversity increases power of comparative genomics
Whole-genome sequencing projects are increasingly populating the tree of life and characterizing biodiversity1–4. Sparse taxon sampling has previously been proposed to confound phylogenetic inference5, and captur...

Open AccessThe tuatara genome reveals ancient features of amniote evolution
The tuatara (Sphenodon punctatus)—the only living member of the reptilian order Rhynchocephalia (Sphenodontia), once widespread across Gondwana1,2—is an iconic species that is endemic to New Zealand2,3. A key lin...

Open AccessDiscovery and population genomics of structural variation in a songbird genus
Structural variation (SV) constitutes an important type of genetic mutations providing the raw material for evolution. Here, we uncover the genome-wide spectrum of intra- and interspecific SV segregating in na...

Article
Open AccessProgrammed DNA elimination of germline development genes in songbirds
In some eukaryotes, germline and somatic genomes differ dramatically in their composition. Here we characterise a major germline–soma dissimilarity caused by a germline-restricted chromosome (GRC) in songbirds...

Open AccessEvolution of heterogeneous genome differentiation across multiple contact zones in a crow species complex
Uncovering the genetic basis of species diversification is a central goal in evolutionary biology. Yet, the link between the accumulation of genomic changes during population divergence and the evolutionary fo...

Article
Open AccessAncient horizontal transfers of retrotransposons between birds and ancestors of human pathogenic nematodes
Parasite host switches may trigger disease emergence, but prehistoric host ranges are often unknowable. Lymphatic filariasis and loiasis are major human diseases caused by the insect-borne filarial nematodes Brug...

Article
Open AccessEvolutionary analysis of the female-specific avian W chromosome
The typically repetitive nature of the sex-limited chromosome means that it is often excluded from or poorly covered in genome assemblies, hindering studies of evolutionary and population genomic processes in ...

The genome of a Mesozoic paleovirus reveals the evolution of hepatitis B viruses
Paleovirology involves the identification of ancient endogenous viral elements within eukaryotic genomes. The evolutionary origins of the reverse-transcribing hepatitis B viruses, however, remain elusive, due ...

Article
Open AccessMesozoic retroposons reveal parrots as the closest living relatives of passerine birds
The relationships of passerines (such as the well-studied zebra finch) with non-passerine birds is one of the great enigmas of avian phylogenetic research, because decades of extensive morphological and molecu...
