I'm currently reading Power, sex, suicide : Mitochondria and the meaning of life as well as Oxygen: the molecule that made the world both by Nick Lane.
They are both damn interesting. P,S,S, It's about endosymbiosis and the formation of the individual. Although I probably just go looking for books that support my ideas it seems to fit with my view that our personalities' are patterns formed by the colonies of Mitochondria. It even presents a theory that the mechanisms for apitosis ( cell death) were originally sex mechanisms of mitochondria which have been adapted to ensure the "Stalinist" (as he calls it) state of the body maintains the individuals survival against cancer or cells that rebel against the individual.
Did you know that some women even have Y chromosomes? It's all the in book.
Oxygen is about the oxygen catastrophe and how it made the rule of the Mitochondria (and thus multi-cellular life) possible and why we all depend on a deadly toxin (O2) for our survival.
