Our bodies are composed of many "weird" body features. In this book, students learn why we experience goose bumps, how fingernails evolved from claws to square and flat and the purpose of our appendix. Each two-page spread includes information on the evolution of body parts, a freaky fact and a sidebar with interesting facts. The book includes a table of contents, a glossary and an index.--Ministry of Education website.
