The evolutionary relationships between modern bird lineages are contentious and have been debated for many years. In order to address this point, the Avian Genomes consortium has sequenced the genomes of 45 species of bird representing 36 orders. Together with the three previously sequenced genomes, these data have helped us resolve the phylogeny of the class Aves. As well as specific insights into bird biology, the wealth of data generated has allowed researchers to answer more general questions about evolutionary biology. A number of articles arising from this project have been published in Science, including the two flagship articles (DOI:10.1126/science.1251385 and DOI:10.1126/science.1253451). The following articles have been published in BioMed Central journals, including Genome Biology and GigaScience. The data from the project are available from GigaDB.
