Part of Zodiac was added later?

[Koen G]

Oh, I remember that video, it was well made 

So you are asking to confirm something you read. But I'm not sure if I understand correctly. Do you mean we know the order in which the sections were written? Or do you mean that first the VM was meant to be only plants, and then (much later?) somebody added all the other sections to it?

This feels like something Lisa Fagin Davis or Rene could say something about.
