FILE - In this Monday, Oct. 31, 2005 picure, a harvester works through a field of genetically modified corn on the dairy farm owned by Al Lafranchi, near Santa Rosa, Calif. Lafranchi started growing the genetically modified corn six years ago, which he says is more resistant to weeds and provides cleaner feed for his dairy cows. For thousands of years, humans have practiced selective breeding. That concept was refined to develop plant hybridization and artificial insemination. Now comes an Atlantic salmon that is genetically engineered to grow twice as fast as a regular salmon. If U.S. regulators approve it, the fish would be the first such scientifically altered animal to reach the dinner plate. less
