![]() Last month, researchers in Australia unveiled the genome of the Tasmanian tiger, the last of which died in captivity in 1936. Scientists are also close to reconstructing the genomes of the dodo, the flightless bird that went extinct from Mauritius, its only home, in the late 1600s and the great auk, which lived in the North Atlantic before dying out in the mid-19th century. The zebra-like quagga was the first extinct species to have its DNA sequenced, back in the genomic Stone Age of 1984, but it’s not up to modern standards. The nearly complete extinct genomes include two human relatives, Neanderthals and Denisovans, in addition to the woolly mammoth, and the passenger pigeon. “The number that’s actually been done is possibly quadruple” the four or five extinct genomes formally reported, “but the results are just sitting in people’s labs.” Journals demand more from papers than “here it is,” said Ben Novak, a co-author of the passenger pigeon study. That the assembly of an extinct genome is being spread like scientific samizdat is not unusual in this field. Morten Erik Allentoft of the Natural History Museum of Denmark, an expert on moa DNA and other extinct genomes, called it “a significant step forward.” Beth Shapiro of the University of California, Santa Cruz, who led a 2017 study reconstructing the genome of the passenger pigeon, called it “super cool” because it “gives us an extinct genome on an evolutionary branch where we hadn’t had any before.” The work on the little bush moa has yet to be published in a journal (the researchers posted a non-peer-reviewed paper on a public site), but colleagues in the small world of extinct genomes sang its praises. “De-extinction probability increases with every improvement in ancient DNA analysis,” said Stewart Brand, co-founder of the nonprofit conservation group Revive and Restore, which aims to resurrect vanished species including the passenger pigeon and the woolly mammoth, whose genomes have already been mostly pieced together.įor the moa, whose DNA was reconstructed from the toe bone of a museum specimen, that might require a little more genetic tinkering and a lot of egg: The 6-inch long, 1-pounder that emus lay might be just the ticket. The achievement moves the field of extinct genomes closer to the goal of “de-extinction”-bringing vanished species back to life by slipping the genome into the egg of a living species, “Jurassic Park”-like. It is now thought that dodos would have been slimmer than they have typically been depicted.Scientists at Harvard University have assembled the first nearly complete genome of the little bush moa, a flightless bird that went extinct soon after Polynesians settled New Zealand in the late 13th century. The Museum also holds two of the most famous paintings of dodos: a copy of George Edwards' colourful 1758 depiction and Jan Savery's 1651 image of a plumper dodo. Today, what remains of the original specimen is the skull with left side of skin, the sclerotic ring from the eye, the skeleton of the foot, the sectioned femur, a feather (removed from the head in 1986) and various tissue samples taken over the years. It is currently not known how the Tradecants acquired their dodo specimen or the extent of the original specimen. This specimen is first listed in 1656 in a catalogue of the Tradescant collection as 'Dodar, from the Island Mauritius it is not able to flie, being so big'. One of the three, the so-called ‘Oxford Dodo’, is a specimen that was part of the Tradescant collection, one of the founding collections of the Ashmolean Museum at the University of Oxford. Only three dodo specimens from this period exist, despite records of living dodos being brought from Mauritius. ![]() The last confirmed sighting of a dodo was in 1662 by the 1700s, it was considered extinct. These animals spread across the island, destroying dodo habitats and eating their eggs. The tale of the dodo’s decline begins in 1598, when Dutch sailors first encountered them. From early accounts, many of the Mauritian birds were tame and easily approached, and so easily caught by humans. But the species’ rapid decline was probably caused by the dogs, cats, rats and pigs that the sailors had brought with them. They lived on fruit and nested on the ground. These birds were about a metre tall and weighed about 20kg. The dodo was a flightless bird, first encountered by Europeans in the late 16th century on the island of Mauritius in the Indian Ocean.
