Genomic Evolution Of Birds
The genomic evolution of birds has come under scrutiny since the advent of rapid DNA sequencing, as birds have the smallest genomes of the amniotes despite acquiring apomorphy and synapomorphy, highly derived phenotype, phenotypic traits. Whereas mammalian and reptile, reptilian genomes range between 1.0 and 8.2 Base pair, giga base pairs (Gb), avian genomes have sizes between 0.91 Gb (black-chinned hummingbird, ''Archilochus alexandri'') and 1.3 Gb (common ostrich, ''Struthio camelus'').Zhang, G., Li, C., Li, Q., Li, B., Larkin, D. M., Lee, C., ... & Ödeen, A. (2014). Comparative genomics reveals insights into avian genome evolution and adaptation. ''Science'', ''346''(6215), 1311–1320/ref> Avian genomes reflect the action of natural selection and are the basis of their phenotypes, reflected in their morphology (biology), morphology and behaviour, which have evolution of birds, evolved significantly since their divergence from other archosaurian, diapsid, and amniotic lineages ...
