My observation is simply that the claim that it doesn't make sense for someone to serendipitously discover that their crops are Roundup-ready isn't really true. Is it the dominant-probability hypothesis? Heck no. It is, however, sufficiently likely that sooner or later it will happen.

In fact, if the genes get out there in the wild, and Monsanto de facto forbids people from discovering this fact, it isn't inconceivable that the genes could spread far and wide without anyone actually noticing until much later.
