Yeah, a shame. But a lot is outdated sadly. In the past 20 years the field of paleo-archeology or paleontology has been revolutionised. So, a lot that Jean Auel wrote back in the 80s and 90s has been changed. For example, Ice Age europeans turned out to be black of skin (some blue eyed); except for the Neanderthals. Blond hair also evolved after the ice ages.
