Dragons of Eden: Speculations on the Evolution of Human Intelligence by Carl Sagan

4.0

Very good considering that Carl Sagan is writing outside of his field. Great speculations on the evolution of human/animal intelligence. Minus 1 star for being heavily outdated (originally published in 1977). I'll definitely be reading a more recent book on the same topic; written by a neuroscientist rather than an astrophysicist.
