Before I write the timeline, I wish to make two things clear. 1. * I write this because I feel there is not enough pre-human history alternate histories. Whilst there are some good timelines, I could barely find one without the label ASB. I hope that in this timeline I can rectify such with science and intelligence, whilst also maintaining a level of understanding that readers can follow. 2. * I am not a plant biologist, nor perfect with the evolutionary history of plants. I research evolutionary biology in animals, however, I believe my recent stint with plant evolution and my understanding of evolutionary history qualifies myself for writing this. However, if it is found to be ASB, I completely understand.
