(4) 4-6 Illustrated by Alfons Kennis & Adrie Kennis. Photographs by Kenneth Garrett. Sloan explains genetic evidence for evolution, early hominid development, theories on how some early humans migrated out of Africa, and the evolution of modern humans. Although the lavish illustrations, including photos, reconstructions, paintings, charts, and diagrams, occasionally interrupt the narrative flow, which itself varies in complexity, they add significantly to the content. Websites. Bib., glos., ind.
