Biology: Science for Life weaves a compelling storyline throughout each chapter, grabbing your attention with current high-interest topics such as genetic testing, global warming and the Zika virus. With this approach, you'll learn the relevant biological principles behind each story and how science can help answer complex questions.

New and updated stories in the 6th Edition make biology concepts relevant and interesting by connecting them to stories you see in the news and decisions you make every day. And with The Big Question feature, you'll practice using data to critically evaluate information. Even if you don't plan to become a practicing biologist, you'll develop critical thinking skills you can use in making decisions about issues that affect your own life, including personal, social and ecological issues.
