Chapter 1 Introduction: Themes in the Study of Life

This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core
theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore
general; however, an effort has been made to include some from each skill level. As in the rest of this
test bank, questions that feature art or those for which several questions follow upon some data or a
scenario are placed together at the end of the chapter.
