[split] Does Voynichese evolve from A to B?

[npcompl33t]

Herbal-A and Herbal-B probably had some difference histories, like being copied from two independent herbals or in two in separate sessions.  So maybe the Author wrote "toxic" in one and used '☠" in the other.   

Or maybe he sorted all plants into harmless ones that can be consumed regularly (Herbal-A) and plants that should be consumed only when needed (Herbal-B), some of them being particularly ☠.

So they wrote about toxic and non-toxic plants in a completely different language? And i take it then that the rosettes is mostly about poisonous things? Come on you are smarter than that.

So yes, I would agree there is progression in the negations as the Rohonc Codex was written.

I realize your answer may be quite speculative, but I am curious what you think. Do you think this is script evolution, i.e. it represents a stable (probably natural) language that was being represented differently, or language evolution, i.e. a conlang that was changing

I would also be interested in your opinion on this Rafal!
