Not much is known about little dodos aside from the fact that they’re in peril, clinging to existence in a narrow patch of forest on the island of Samoa with likely fewer than 200 individuals remaining. Yes, little dodos are alive, but they are not well. While there are no intact dodo cells left today, scientists have retrieved bits of dodo DNA from a specimen stored at the University of Oxford.

Or dodos may have gone hungry as the invaders cleared forests rich in fruits. Some were killed by sailors looking for a change in diet, others by the rats, cats, pigs and monkeys the sailors brought with them. The dodo’s closest genetic relative was the also-extinct Rodrigues solitaire. The dodo (Raphus cucullatus) is an extinct flightless bird that was endemic to the island of Mauritius, which is east of Madagascar in the Indian Ocean. These sailors, and others to come, quickly decimated the dodo population as an easy source of fresh meat for their voyages. The birds had no natural predators, so they were unafraid of humans. The birds were discovered by Portuguese sailors around 1507. The cause of the dodo’s extinction is not entirely clear. The dodo is a close relative of modern pigeons and doves. The dodo, which is now extinct, lived on fruit and nested on the ground. The adaptive features of organisms could now be explained, like the phenomena of the inanimate world, as the result of natural processes, without recourse to an Intelligent Designer. With Darwin’s discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science. It was first found by scientists in 1832, when it was said to be so full of animal bones that you only had to dip your hands into the water to retrieve them. “Preventing species from going extinct in the first place should be our priority, and in most cases, it's a lot cheaper,” said Worm.An ancient swamp full of fossils from extinct animals was discovered in Mauritius. It helps if they can learn from other wild animals of their kind - an advantage that potential dodos and mammoths won't have, said Boris Worm, a biologist at the University of Dalhousie in Halifax, Nova Scotia, who has no connection to Colossal. On a practical level, conservation biologists familiar with captive breeding programs say that it can be tricky for zoo-bred animals to ever adapt to the wild. “And where on Earth would you put a woolly mammoth, other than in a cage?” asked Pimm, who noted that the ecosystems where mammoths lived disappeared long ago. “There's a real hazard in saying that if we destroy nature, we can just put it back together again - because we can't,” said Duke University ecologist Stuart Pimm, who has no connection to Colossal. Other scientists wonder if it's even advisable to try, and question whether “de-extinction” diverts attention and money away from efforts to save species still on Earth. The concept is still in an early theoretical stage for dodos.īecause animals are a product of both their genetics and their environment - which has changed dramatically since the 1600s - Shapiro said that “it's not possible to recreate a 100% identical copy of something that's gone.” It may be possible to put the tweaked cells into developing eggs of other birds, such as pigeons or chickens, to create offspring that may in turn naturally produce dodo eggs, said Shapiro. The team may then attempt to edit Nicobar pigeon cells to make them resemble dodo cells. Her team plans to study DNA differences between the Nicobar pigeon and the dodo to understand “what are the genes that really make a dodo a dodo,” she said. Shapiro is paid by the Howard Hughes Medical Institute, which also supports The Associated Press’ Health and Science Department. ![]() The dodo's closest living relative is the Nicobar pigeon, said Beth Shapiro, a molecular biologist on Colossal's scientific advisory board, who has been studying the dodo for two decades.
