Ancestral vertebrate genome

It has been proposed that more than 450 million years ago, two successive whole genome duplications took place in a marine chordate lineage before leading to the common ancestor of vertebrates. A precise reconstruction of these founding events would provide a framework to better understand the impact of these early whole genome duplications on extant vertebrates.

Bird mitogenomes differ from other vertebrates in gene rearrangement. The most common avian gene order, identified first in Gallus gallus, is considered ancestral for all Aves. However, other rearrangements including a duplicated control region and neighboring genes have been reported in many representatives of avian orders.
