What if, in the near future, herds of giant mammoths roam the Siberian tundra again? Or if powerful aurochs graze in German pastures? Will it one day actually be possible to clone dinosaurs? If so, would that really be a good idea? Scientists around the world are trying to find answers to these questions and are working to resurrect long-extinct species. Some research out of pure curiosity, while others believe that the return of these species could enrich our ecosystems and serve as a successful weapon in the fight against climate change. Torill Kornfeldt speaks with people who are attempting to clone extinct species using DNA from bone finds or frozen cells, and with the help of boundless imagination. She explores the impacts these experiments could have on our environment and humanity.
