To address this challenge, we assembled or collected the genomes of 48 avian species spanning most orders of birds, including all Neognathae and two of the five Palaeognathae orders, and used the genomes to construct a genome-scale avian phylogenetic tree and perform comparative genomics analyses (Jarvis et al. in press; Zhang et al. in press). Here we release assemblies and datasets associated with the comparative genome analyses, which include 38 newly sequenced avian genomes plus previously released or simultaneously released genomes of Chicken, Zebra finch, Turkey, Pigeon, Peregrine falcon, Duck, Budgerigar, Adelie penGigaScienceComparative genomic data of the Avian Phylogenomics Project.PMC4322804DP1 OD000448Zhang GJarvis EDAvian Genome ConsortiumLi CLi BWang JGilbert MTfalseComparative genomic data of the Avian Phylogenomics Project.<h4>Background</h4>The evolutionary relationships of modern birds are among the most challenging to understand in systematic biology and have been debated for centuries.
