Single mutations venture into an unforgiving ecosystem and test their mettle.
Whatever doesn't work gets recalled by the Manufacturer. Among other recent unpleasant surprises, spliced genes seem unusually likely to spread to other organisms. Canola pollen can waft spliced genes more than a mile, and common crops can hybridize with completely unrelated weeds. But there is evidence that the crops may have an impact not just on the pests, but on beneficial insects such as bees, lacewings, and ladybirds and the birds that eat them. By contrast, caterpillars fed with conventional pollen all survived.
