Genetically modified canola has escaped from the farm and is thriving in the wild across North Dakota, according to a study that indicates there are plenty of novel man-made genes crossing the Canada-U.S. border. GM canola was found growing everywhere from ditches to parking lots, the scientists report, with some of the highest densities along a trucking route into Canada. [...] At almost half of the 634 stops they found genetically modified canola. At some locations there were thousands of GM plants growing. [...] Perhaps most significant, they said, is the fact that two of plants had combinations of herbicide resistance that had not been developed commercially. “That suggests to us there is breeding going on, either in the field or in these roadside populations, to create new combinations of traits,” said Sagers. “In terms of evolutionary biology it’s pretty amazing.”
