We are thrilled to introduce the second edition of Scientific American Biology for a Changing World. We have replaced six stories and added two new Milestones to keep this book at the forefront of current issues in biology. New Driving Questions target students’ reading, and new mini cases and data questions test their knowledge. A fresh, updated design showcases our unparalleled Infographics, and compelling narratives continue to reveal how biology is relevant to daily life.
As with the first edition, we could not have completed this project without the help of a great team at W. H. Freeman. The authors would like to thank Elizabeth Widdicombe, Susan Winslow, and the folks at W. H. Freeman and Company and Scientific American for continuing to support this vision for biology education. They recognized our diverse strengths and brought us together to make this vision a reality. We continue to learn so much from one another on this challenging and rewarding professional journey, and none of us has likely worked so hard and so passionately on a project as we all have on this one.
We would like to thank all those who were interviewed and who generously contributed information for the chapters in this edition. Their stories are central to the impact that this book will have on the students we teach. They are authentic examples of biology in a changing world, and they bring this book to life.
A special thank you is required for our Acquisitions Editor, Beth Cole, for her unwavering encouragement and ability to bring stable direction and support to the project. Development Editor Andrea Gawrylewski has spent many hours in the pages of this book, editing the details, managing our chaos, and smoothing our rough edges. Sara Blake and Jane Taylor were invaluable in the scheduling, reviewing, and managing of this edition. We thank them for their dedication, patience, experience, and expertise. Thanks go to Betsye Mullaney and Amanda Dunning for their tireless work on our media and assessment program.
Many thanks to Liz Geller, Nancy Brooks, Diana Blume, Matthew McAdams, Christine Buese, Paul Rohloff, and all the people behind the scenes at W. H. Freeman for translating our ideas into a beautiful, cohesive product. We would like to thank Rachel Rogge and Jan Troutt at Precision Graphics for their outstanding work on the Infographics. We appreciate their patience with the many edits and quick timelines throughout the project. They do amazing work.
We’d like to thank John Britch and Shannon Howard for their enthusiasm and hard work in promoting this book in the biology education community. We thank the enthusiastic group of salespeople who connect with biology educators across the country and do a wonderful job representing this book.
We would like to thank our families and friends who have been close to us during this process. They have been our consultants, served as sounding boards about challenges, celebrated our successes, shared our passions, and supported the extended time and energy we often diverted away from them to this project. We are grateful for their patience and unending support.
And finally, a sincere thank you to our many teachers, mentors, and students over the years who have shaped our views of biology and the world, and how best to teach about one in the context of the other. You are our inspiration.
