Wasps Have Injected New Genes Into Butterflies

sciencehabit writes: If you're a caterpillar, you do not want to meet a parasitic wasp. The winged insect will inject you full of eggs, which will grow inside your body, develop into larvae, and hatch from your corpse. But a new study reveals that wasps have given caterpillars something beneficial during these attacks as well: pieces of viral DNA that become part of the caterpillar genome, protecting them against an entirely different lethal virus. In essence, the wasps have turned caterpillars into genetically modified organisms.
