Humans: The Neanderthal Parallax, Book 2 (Unabridged‪)‬

In this Hugo-nominated novel, Neanderthal physicist Ponter Boddit brings Canadian geneticist Mary Vaughan back to his world to explore the near-utopian civilization of the Neanderthals. Boddit serves as a Candide figure, the naive visitor whose ignorance about our society makes him a perfect tool to analyze human tendencies toward violence, over-population, and environmental degradation. The Neanderthals have developed a highly artistic, ethical, and scientific culture without ever inventing farming - they're still hunters and gatherers - and this allows the author to make some interesting and generally unrecognized points about the downside of the discovery of agriculture.
