After Its Own Kind

From Truth Farmer:

Never in nature has a spider or a human crossed with a goat, a human with a cow, nor has a mouse coupled with a pig, or a fish combined with a cat. Nor has a bacterium inserted itself into a plant or a chemical herbicide entered the germplasm of a plant and propagated itself.

Whether it is strictly correct or not that no genes from one species have every been naturally inserted into the genes of another, completely unrelated species, Truth-Farmer's point is undeniable. Deliberate genetic modification isn't even close to the same thing as selective breeding or natural selection (whatever that is). Living organisms are extraordinarily complex marvels of engineering, and people messing around with them are like five-year-olds thinking they can improve on a Frank Muller watch using wooden mallets and finger paints.
