I'd also like to recommend Power, Sex, Suicide by the same guy, Nick Lane.

It's an absolutely amazing book that explains the origins of mitochondria, why they're necessary for complex life (and this means that complex life is exceedingly rare in the universe), and all sorts of effects the differing genomes of mitochondria and cells have: fertility, aging, and a bunch of other ones.

If you're interested in cellular biology, read this guy.
