Query: Ludicrous, even as fiction

This book is sophomoric science (high school, not college). Where did Dalton get his research material, the "Just So" series. The movie rights have been picked up by Spielberg, which is appropriate, because the science in "Neanderthals" is on the same level as "Jurassic Park", almost non-existent. No wonder America is dumbing down, we read (and apparently believe) too much pseudo-intellectual fiction, and have almost no comprehension of science fact
