Science of resurrection of species. How to clone a mammoth

We dream of living forever. We hope that we can clone your favorite pet, as happened with Dolly"s lamb. We want to take a walk in the Jurassic Park, look at dinosaurs and mammoths, see the extinct MOA, Drroths, and other creatures. Bet Shapiro, a professor at the Faculty of Ecology and Evolutionary Biology of the University of Santa Cruz in California, tells us an exciting history of modern science of recreation of species. As soon as any organism dies, its DNA immediately begins to collapse under the influence of ultraviolet radiation and bacteria, so you can’t just take a cage and clone an extinct animal. Researchers have to deal with a difficult task - they are trying to fold a puzzle in which part of DNA slices are lost. Let"s figure out if we need to revive the disappeared species (Beth Shapiro is sure that it is worth), what difficulties await us along this path and what it can lead to
