Tony: (Bear in mind that I do believe plants came first an in great quantities long before animals, I am just questioning the huge time frame for the move from simple to complex plant organisms.)

>David: The explosion in the type of plants we have today occurred 100 million years or more after the Cambrian. I forget the exact time frame. Simpler plants certainly flourished long before that.-So we had a few billion years where plants could have exploded into infinite variety and complexity, with an atmosphere that was conducive to them, but they didn't.
