WASHINGTON – We've always played with our food — even before we knew about genes or how to change them.
For thousands of years, humans have practiced selective breeding — pairing the beefiest bull with the healthiest heifers to start a new herd. That concept was refined to develop plant hybridization and artificial insemination. Today we've got tastier corn on sturdier stalks, bigger turkeys and meatier cattle.
