George Church, a geneticist at Harvard Medical School is already working on "resurrecting" the mammoth so to speak. Using CRISPR/Cas9 technology genes are able to be edited easily. He has identified 14 genes that may be correlated to cold tolerance. This may be the beginning of bringing back the wooly mammoth or modifying Asian elephants to have mammoth qualities. An actual mammoth-like elephant roaming the arctic is years away, but the genome research is incredibly interesting.
