DNA from the largest bird ever sequenced from fossil eggshells

Even extinction and the passing of millennia are no barriers to clever geneticists. In the past few years, scientists have managed to sequence the complete genome of a prehistoric human and produced “first drafts” of the mammoth and Neanderthal genomes. Now, a variety of extinct birds join the ancient DNA club including the largest that ever lived – Aepyornis, the elephant bird.

In a first for palaeontology, Charlotte Oskam from Murdoch University, Perth, extracted DNA from 18 fossil eggshells, either directly excavated or taken from museum collections. Some came from long-deceased members of living species including the emu, an owl and a duck. Others belonged to extinct species including Madagascar’s 3-metre tall elephant bird and the giants
