Neanderthal Parallax

Neanderthals have developed a radically different civilization on a parallel Earth. A Neanderthal physicist, Ponter Boddit, accidentally passes from his universe into a Canadian underground research facility. Fortunately, a team of human scientists, including expert paleo-anthropologist Mary Vaughan, promptly identifies and warmly receives Ponter. Solving the language problem and much else is a mini-computer, called a Companion, implanted in the brain of every Neanderthal. But it can't help his fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.

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.

Scientists (and lovers) Mary Vaughan, who is human, and Ponter Boddit, who is Neanderthal, embark on the harrowing adventure of conceiving a child together. To overcome the genetic barbed wire of mismatched chromosomes, they must use banned technology obtainable only from a Neanderthal scientist living in the northern wilderness.
