Life from an RNA World: the ancestor within

Life from an RNA World: The Ancestor Within is a great place to find all of the arguments for the existence of an “RNA World” neatly compiled in a short and fluid book. I read this pithy work in only a few days while commuting back and forth on public transit. Consequently my first reaction regarding the best audience for the book was that it was for non-scientists, or for those with a basic knowledge of biology but not getting paid to be a scientist. For me it was a smooth, easy read, and I imagine that many of my fellow passengers on the bus or the train saw me nodding my head spontaneously on many occasions.
