The movement for the resurrection of previously extinct species has been seeing a lot of progress lately. A reason for this progress is the development of the CRISPR/ Cas9 system and because of synthetic biology. CRISPR stands for, Clustered Regularly Interspaced Short Palindromic Repeats and it enables scientists to easily edit the DNA of any genome. Scientists have come close to recreating the wooly mammoth that became extinct almost 4,000 years ago. Synthetic biology, in this case, includes splicing the genes of a wooly mammoth with those of an Asian elephant to produce a mammoth-elephant hybrid. I think people want to bring the mammoth back because of its beauty and the fact that they can say that it has been done. I think the attention that the woolly mammoth will get will take away from other animals that are being hunted, giving them time to restore their numbers. There could be a couple of disadvantages to bringing the woolly mammoth could be that the mammoth could be dangerous, or they could take over the resources of another animal that lives in the area, possibly rendering that species extinct. The reasoning behind picking the Asian elephant is because it shares over 99% of the DNA with the wooly mammoth. Scientists want to bring back this animal because of its majestic features and because it can protect the Asian elephant from further exploitation from hunters. In addition, the woolly mammoths would start to graze on the Arctic tundra which would expose the earth underneath to cold air, keeping it frozen longer and combatting climate change.
