I have written a book about why new things happen, here’s a pdf. There is a short summary at the front. If you would like to buy a paper copy or higher quality Ebook-style pdf, please visit the amazon profile:
Or buy directly from the publisher (University Press of America) here: https://rowman.com/ISBN/9780761867081/Natural-Novelty-The-Newness-Manifest-in-Existence
Thanks for your interest.
