Gastro-Yuxi toad, a precious amphibian distributed only in southeastern Queensland, Australia, belongs to the tortoise toad family, first discovered in 1972, by 1983 it was considered extinct, but they left some body tissues to be preserved by humans, and today's cloning technology has a great chance of reviving the gastro-yuxi toad.
The dodo, which is considered a fat, stupid image, is also called the dove, living in the Mauritius region of the Indian Ocean, became extinct at the end of the 17th century, and experts have successfully extracted the dodo's still vital DNA, which also shows that the dodo is hopefully resurrected and returned to Earth.
The white-tipped dolphin, a freshwater cetacean special to China's Yangtze River Basin, is a small whale that has been extinct for many years and is even considered extinct, but there are still a very small number of living animals left, and the increasingly perfect cloning and transgenic technology may be the last hope of saving the white-tipped dolphin.
North American passenger pigeon, the most famous representative of the modern extinct birds, was once a large number of birds in North America, due to human hunting and other reasons to become extinct, in essence, scientists can use the existing close relatives of north American passenger pigeons to create a hybrid pigeon, although not a real passenger pigeon, but the closest.
Mammoth, one of the largest elephants in history, weighing up to 12 tons, was once distributed in Europe, Asia, and the northern region of North America, and experts have found a basically intact mammoth in the Siberian permafrost, and even found frozen corpses more than once, which also adds to the possibility of mammoth resurrection.
