Fifteen years ago, Dolly the sheep came to our world and caused a real sensation with its appearance. A living, breathing sheep created from a single cage, Dolly wasn't the world's first cloned animal, but she did become the most famous.
After Dolly was born, many scientists predicted the possibility of cloning all types of animals, including humans. Everyone knows about Dolly, but few people know that tadpoles were the first cloned creatures, and the process itself took place in the 1950s.
However, despite a number of successes achieved in this area (for example, the successful cloning of cows and mice), the data show that specialists have not been able to clone every animal species, as many scientists hoped. Some successes continued for a very short period of time, as cloned animals died almost immediately after birth. And some of the efforts, which were initially promising, have so far come to nothing.
However, achievements in this area are still significant, because over the past 5-10 years, technologies have reached a new level. Using these tools, scientists still dream of creating a world where endangered animals are saved from extinction and extinct species can be miraculously brought back to life. Will our planet ever see mammoths again? Anything's possible.
