Found Things: Evolution- The First Four Billion Years

My father sent me a copy of Evolution:  The First Four Billion Years. Looks like it's going to be a great (if long) read.  The book is bifurcated into a series of long essays on various major topics in the theory, followed by a collection of shorter essays on various thinkers, works and notable organisms.  I'm about 40 pages in, only about 900 left. The only problem that I can see is that the damn thing starts to agitate the wrist after holding it for too long.  Oh well.  Knowledge awaits.
