Absolutely one of the best books I ever read, by one of the greatest scientists in the world. An easy read where I learned a lot. Might not be for everyone, but definitely for everyone interested in science. I only wish it was longer!...But now I'm working on one of his other books, "Superorganism", which is huge.
