This ambitious exploration of archaeology approaches the popular subject through four important discoveries of hominin skeletons in the past 30 years. The famous finds, located on three continents and dated 1.6 million to 5,300 years old, include Turkana Boy, the most complete Homo erectus yet discovered; Lapedo Child, a Paleolithic ritual burial; Kennewick Man, whose bones became the subject of a major legal battle; and the Iceman, which had skin as well as bones preserved under a glacier. Since each of the discoveries could merit an entire book, the coverage is at once tantalizing and frustrating. The authors, both professors, provide a narrative about each discovery, describe the process of studying the remains and discuss scientific debates about broad implications of the finds. They tackle large topics in too little space while also straining to add a conversational tone that sometimes falls flat. The study’s strength is in the fascinating details and in its potential for inspiring readers to learn more. Unfortunately, suggestions for further reading are primarily books written for adults, although website recommendations are more helpful. Infrequent color photographs add information.
