Mammoths from the Ice Age are to be "resurrected" by 2028: scientists plan to bring back the Dodo and Tasmanian tiger. What is known

Scientists said they want to "resurrect" a mammoth from the Ice Age, as well as a Tasmanian tiger, a giant bear, a Dodo bird, a one-and-a-half-meter beaver, and others. The scientists aim to realize their first plans by 2028.

Colossal Biosciences, the world's first company dedicated to eliminating extinction, has taken on such an ambitious project. Scientists have compiled a "very long list" of animals they hope to bring back to the modern world, TheSun reports.

Over the three years of Colossal Biosciences' existence, several high-profile projects have been launched. The first was the work on the revival of the woolly mammoth, which is still ongoing. In 2022, Colossal announced a partnership with the Thylacine Integrated Genetic Restoration Laboratory (TIGRR for short) to revive the Tasmanian tiger or thylacine.

Both species were mammals, which makes the work of scientists somewhat easier. They use the same reproductive principles for recovery. Scientists minimally change the genetic code of the embryo in the egg of the nearest species. They do the same with the embryos of the animal that grew out of it, and so on.

The CEO of the gene-editing company Colossal Biosciences said that their immediate plans also include the "resurrection" of the Dodo bird, which was once eaten by humans.

For prehistoric elephants and tigers, the revival scheme is already known, but with birds, experts say, it is more complicated. After all, the stage of development at which scientists make genetic changes takes place in the egg and is so fast that it is very difficult to catch it.

Prof. Beth Shapiro said she is also looking forward to the revival of large bears. "One of my favorite extinct species is Arctodus, the giant short-faced bear that was over 4 meters tall, and also the great beaver that lived in North America," she said.

Scientists have high hopes for the "resurrection" of the giant bear, which was considered the largest land species inhabiting North America. The fluffy herbivore would have been equal to a human standing on its four legs.

Among the interesting options for recovery are also the great beavers, which became extinct about 10,000 years ago. Thanks to the remains found, it was realized that these rodents had 15-centimeter teeth and could swim underwater.

Colossal scientists emphasize that their first project, the restoration of the woolly mammoth, will be ready by 2028.
