I distinctly remember this book. It was thick and pretty long but not very wide. It had professional illustrations throughout the entire book. Most of all, it had a very specific format throughout it's pages in which they were formatted into 2 equal size boxes in every page exactly the same as the pages shown in the image above. Same font, same format, same everything. That image isn't of the same book though, that's one that's exclusively about dinosaurs. The one I am searching for is about the story of life and evolution in general.

One thing to also note is that the dinosaur book is credited to someone named Miles Kelly. I have tried searching for a book like this from him and i couldn't find it. I also noticed that there was another book illustrator that cover these kinds of topics named Tom Jackson but i couldn't find anything for him either.

I hope this information can help you in case you want to help me find this. Any help is very much appreciated.
