An interpretation of the Voynich manuscripts. Crossing reptiles and plants. (Page 5.)
In this update to Plant to human, we will be looking at a undefinable plant. This image to me displays the top blackened part of the flower as being the brain of this plant. With a single stem like connection to the stem of the plant body. In others words it is simply described by the bud of the flower controlling what the plant does, whether it should make new or continue support the current flower.
This root systems describes quite a lot for this theory point of view. It has feather pen strokes on the right side of the root system. The right side could be related to the right side of the brain or the creative side and the ability to think/fly freely.The claw or beak like points protruding from the right side root also leads me to believe this is where modern bird brains where also formed. As for the left side of the root system it has scale like pen strokes, which could correlate to modern day fish. (With the thinking most probable survivors would have been flying reptiles after any apocalyptic events. From the description on page 2.) After making the first correlation to the right side of the root system when doing so with the left side it also holds true. With fish being highly analytical. They can feel vibrations and strike preciously.
Post overview, being even fish and birds evolved from plant life. Plants had two major thinking and processing organs
