In Siberian Belaja Gora, scientists have found numerous mummified glaciers. Among other things, parts of several mammoths, whose DNA can hopefully lead to the reproduction of the animal. Genetics professor George Church has been working on the project since 2008.
By exchanging the genes for, for example, fat storage, shape of the baits and hair, he hopes to create a hybrid between elephant and mammoth.
- A year ago, I thought we would see embryo-like structures within two years. I still believe that, says George Church in the world of science.The goal: 100,000 mammoths
The goal is for mammoths to be reintroduced into the Siberian ecosystem - something that can be positive for the environment.
The theory is that a reintroduction of the mammoth should reduce the forest area of the tundra, preventing the permafrost from thawing. With the hive left in the ground, greenhouse gas methane is prevented from being released, which reduces the effect of global warming.
"To keep the permafrost, the herds need to be made up of about 100,000 mammoths," says George Church in the World of Science.
