"Ah, okay, it's - the thing is that's - kind of not a sensible question by itself; it's like asking what the difference between . . . people, or species of plants - plants is probably the better example there - is. You can point at any two and talk about how they're the same and how they're different, and you can talk about traits that all plants have, and traits that groups of plants have - like maybe crops specifically, for how I thought maybe you were asking about the generally-available ones - or ways that plants definitely aren't, and - plants that could maybe exist but don't yet? But not - that, I don't think. - Unless I misunderstood again? This is very complicated and I'm not a researcher - or for that matter a botanist - and I don't think I'm very good at explaining things."
