Over two-thirds of birds exhibit a highly distinctive, ‘signature’ gross genomic structure, typically ~10 macrochromosomes and ~30 morphologically indistinguishable microchromosomes, despite, or perhaps facilitating, a huge range of phenotypic diversity. Correlating genome sequence to karyotype (chromosome-level assembly) is an essential prerequisite to address a range of biological and evolutionary questions, a process impeded by this highly fragmented organizational structure. This talk will chronicle contemporary efforts to construct chromosome-level assemblies and evolutionary pathways in multiple avian species and the biological significance of the findings. The wider utility of such approaches and how they provide a glimpse into the genome structure of the forbears of birds, the dinosaurs will be discussed.
