Determining the timing of diversification of modern birds has been difficult. We combined
DNA sequences of clock-like genes for most avian families with 130 fossil birds to generate …

Current understanding of the diversification of birds is hindered by their incomplete fossil
record and uncertainty in phylogenetic relationships and phylogenetic rates of molecular …

The phylogeny and divergence timing of the Neoavian radiation remain controversial
despite recent progress. We analyzed the genomes of 124 species across all Neoavian …

To better determine the history of modern birds, we performed a genome-scale phylogenetic
analysis of 48 species representing all orders of Neoaves using phylogenomic methods …

Deep avian evolutionary relationships have been difficult to resolve as a result of a putative
explosive radiation. Our study examined∼ 32 kilobases of aligned nuclear DNA sequences …

The early evolution of living birds has been sharply debated, with two disparate
interpretations. Molecular-clock studies consistently date the emergence of modern bird …

Despite tremendous efforts in the past decades, relationships among main avian lineages
remain heavily debated without a clear resolution. Discrepancies have been attributed to …

Current global patterns of biodiversity result from processes that operate over both space
and time and thus require an integrated macroecological and macroevolutionary …

Birds are among the most diverse and intensively studied vertebrate groups, but many
aspects of their higher-level phylogeny and evolution still remain controversial. One …

Background The origin of birds is one of the most enduring and dramatic evolutionary
debates. The hypothesis that the primarily small-sized birds are nested within a theropod …
