Survival of the Sickest by Sharon Moalem

We own this book but I listened to it while I did yard work. It wasn't the most captivating book I've ever read, but it was interesting. The idea of evolution was told through the eyes of germs and all sorts of little animals and plants! There is an explanation for why diabetes was important at one point of history. I don't remember the specifics of what I read, but I was fascinated by it at the time. Definitely not a "beach read", but a nice book for a change of pace.
