Finally, someone came along and articulated my view that fearing gene-modified foods is silly. Richard Dawkins, noted geneticist and inventor of the “meme” meme, wrote this:

The genetic code, on the other hand, with a few very minor exceptions, is identical in every living creature on this planet, from sulphur bacteria to giant redwood trees, from mushrooms to men. All living creatures, on this planet at least, are the same “make”.

The consequences are amazing. It means that a software subroutine (that’s exactly what a gene is) can be carried over into another species. This is why the famous “antifreeze” gene, originally evolved by Antarctic fish, can save a tomato from frost damage. In the same way, a Nasa programmer who wants a neat square-root routine for his rocket guidance system might import one from a financial spreadsheet. A square root is a square root is a square root. A program to compute it will serve as well in a space rocket as in a financial projection.

…What this means is that there is a case to be made on both sides of the argument, and we need to exercise subtle judgment. The genetic engineers are right that we can save time and trouble by climbing on the back of the millions of years of R & D that Darwinian natural selection has put into developing biological antifreeze (or whatever we are seeking). But the doomsayers would also have a point if they softened their stance from emotional gut rejection to a rational plea for rigorous safety testing. No reputable scientist would oppose such a plea. It is rightly routine for all new products, not just genetically engineered ones.
