In discussions of manipulated farm animals one sometimes hear references to pigs with an extra vertebra, "so that the farmers can get an extra pair of spare ribs out of the pigs". Is this true, and how has this extra vertebra gotten there (since I've heard the story since long before the advent of recombinant DNA-technology)? --- d85-kai@nada.kth.se
