When extinction is a good thing We have developed genetic technologies that could wipe out harmful pests like mosquitoes or flesh-eating screwworms. We should start to use them, says Michael Le Page IN A few cases, the extinction of a species would be a positive. That’s a controversial opinion, but I do think the world would be better off, for instance, without malaria-spreading mosquitoes. Gene drives are pieces of DNA that include genes that somehow ensure that more than half of offspring inherit them. For instance, some work by slowing down rival sperm that don’t carry the gene drive. The CRISPR gene drive created by Esvelt works by copying and pasting itself from one chromosome to another. …
