When the species was lost, the forests lost the main driver of their regulation cycle and have never been the same. Reviving extinct keystone species, then, could help us preserve biodiversity, and, possibly, the ecosystems as a whole. Focusing on de-extinction could compromise biodiversity by diverting resources from preserving ecosystems and preventing newer extinctions. It could also reduce the moral weight of extinction and support for endangered species, giving the false impression that reviving an extinct animal or plant is trivial. Woolly mammoths seem like an excellent choice for de-extinction. Many woolly mammoth specimens remain in the permafrost of Siberia. Paleogeneticists, scientists who study preserved genetic material, have sequenced the woolly mammoth genome.
