Richard “Selfish Gene” Dawkins explains why transgenic imports don’t deserve the bad rap they’ve been getting.
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.
