Project leader Professor Alan Cooper from the University of Adelaide's Australian Centre for Ancient DNA (ACAD) said that New Zealand is recognised as one of the world's "great evolutionary laboratories" due to the absence of land mammals and the radiation of giant flightless birds such as the moa.
Research done in part at the ROM using ancient DNA sequences revealed that the dodo was part of an ancient radiation of doves that spread across the Indian Ocean.
Although the last reliable sighting of a living dodo was in the late 17th century, it may one day be possible to reconstruct the species with the ancient DNA from one of these bones.
