The decision is not a full-throated endorsement of the practice, but it could nonetheless have wide implications. Researchers are already pursuing projects that involve changing some species’ DNA. Scientists are genetically modifying mosquitoes to reduce transmission of diseases like malaria, for example, and synthesizing horseshoe crab blood, which is used in drug development. Controversial efforts to “de-extinct” archaic creatures — such as the so-called “dire wolf” that a biosciences company announced it had revived this spring — fall under the umbrella, as well. So do possibilities like modifying organisms to help them adapt to a warming world, which are on the table but further off in development.
