New Zealand claims back the Kiwi after ancient DNA testing

Almost 20 years ago, Alan Cooper from the Australian Centre of Ancient DNA found that the Kiwi might actually originate from Australia.

Given that the emu and cassowary are the Kiwis closest living relatives and that New Zealand split off from Australia when Gondwana broke up, this was a logical suggestion.

Alan Cooper is from New Zealand himself and says: “This was a huge psychological blow in New Zealand and extremely unpopular”.

A new paper published today in Science sets the record straight. Alan Cooper and his team have been able to analyse the ancient DNA of two extinct birds from Madagascar and have found the Kiwis to be their closest relatives.

The emu, cassowary, ostrich, rhea and kiwi are known as “ratite birds” they can’t fly because they have lost the bone that wing muscles can attach to. The fact that the DNA of the kiwi closely matches the DNA of the extinct elephant bird from Madagascar means that birds of kiwi lineage must have flown at some point to get from Madagascar.

The connection between these birds undermines the idea that ratites evolved from ancestors that didn’t fly.

“Twenty years later it’s great to be able to show using ancient DNA that the kiwi is not an Australian bird. In fact its closest relative is the elephant bird from Madagascar,” he says.

“The New Zealanders will be much more comfortable with that. It’s their worst nightmare to be a derivative of Australia.”

Genographic Project Results

Listen to Prof Alan Cooper reveal the results from a recent Genographic Project event held in Adelaide.

The Genographic Project results were ‘revealed’ to participants last Tuesday 7 December at an event held at the Science Exchange, RiAus.

Listen to Prof Alan Cooper and Dr Wolfgang Haak (University of Adelaide) and visiting Prof Carles Lalueza-Fox (Institute of Evolutionary Biology, UPF, Barcelona) as they examine the results of the Adelaide public swabbing and discuss the ancient ancestry of national identities who participated in the project.

Access audio files from individual speakers.

You can also view video footage from this event through the RiAus website.

Bringing back bits from the dead.

Mammoth haemoglobin has been successfully resurrected by a team including scientists from ACAD.

Professor Alan Cooper, the Director of the Australian Centre for Ancient DNA was part of a team of scientists who have resurrected mammoth haemoglobin using ancient DNA preserved in 25,000 to 45,000 year old bones.

Watch the clip below to learn how the scientists produced the mammoth haemoglobin.
