> Graham thinks that these sequences are “definitive proof” that a small chunk of a herring chromosome made its way into a smelt’s. “If anybody wants to dispute this,” she said, “you know, I don’t see how they possibly could.” I think the problem here is she is presenting something that is unfalsifiable and therefore problematic. I think it would then be on her and her team (or someone else who cares enough) to prove that it is possible somehow. Devise an experiment (a very clever one I'm sure) of some type that proves that DNA can be passed on this way somehow.
