Sách nói: Early Cave-Men

The People Who Wanted To Live in Caves. This little book takes us back to the time when our ancestors lived, or wanted to live, in caves. Unfortunately the caves of that time were mostly used by large animals like the Sabre Toothed Tiger and bears who could easily kill and eat our ancestors. Thus the subtitle of this book is The Age of Combat. This book, aimed at children, tries to show how certain things could have taken place to enable our species to eke out a living alongside the much stronger beasts, such as why we wanted to live in caves; the hazards and rewards of living in caves; the taming of fire; and how early tools were invented. This book follows on The Tree Dwellers, and is followed by The Later Cave-Men. - Summary by Phil Chenevert
