The Orlando Sentinel is reporting that a new 10-year study has settled (again) the question of whether genetically improved plants will eventually become unstoppable super-species and crowd out unaltered varieties, as some fear-mongers had predicted. After four years, genetically improved corn, rapeseed (canola), and sugar beets died out naturally. Within a decade, even the hardiest of transgenic potatoes showed no signs of their previously altered genes.
