In de-extinction scenarios, the value of CRISPR lies in precise rewriting: researchers use the genome of a closely related species (such as the Asian elephant) as the chassis and edit in, one by one, the key difference sites inferred from the residual DNA of the extinct species (such as the woolly mammoth).

UnverifiedDe-extinction is not simply cloning extinct animals, but first extracting genomes from closely related species, then comparing them with DNA fragments of the extinct species, and gradually editing out a genome close to the original species, involving massive data processing, multi-dimensional simulation of gene interactions and long experimental validation cycles.79% similarUnverifiedGene editing tools such as CRISPR may cut other similar sequences elsewhere in the genome when cleaving target gene sites, triggering off-target effects and potential carcinogenic risks.65% similarUnverifiedForensic Genetic Genealogy works by uploading DNA extracted from remains to genealogy databases and identifying the person by tracing kinship relationships.62% similarUnverifiedReviving extinct species could disrupt the balance of existing ecosystems, triggering chain reactions.58% similar
