Nick Lane has published a new book of tremendous scope. He asks how life got to be the way that it is. This is a great evolutionary question and Nick deals with everything from the beginning of life to the present day.
I have a copy of it and it is a superb read by a scientist (and yes, Nick publishes his own research in peer-reviewed articles in very fine journals) at the very top of his game.
