Biology, 8th Edition
Much has changed in the world since the completion of the previous edition of BIOLOGY. In the realm of the biological sciences, the sequencing of the genomes of many more species has had deep ramifications in diverse areas of research, providing new insights, for example, into the evolutionary histories of numerous species. There has been an explosion of discovery about small RNA molecules and their roles in gene regulation and, at the other end of the size spectrum, our knowledge of Earth’s biodiversity has expanded to encompass hundreds of new species, in· eluding parrots, monkeys, and orchids. And during the same period, biology has become more prominent than ever in our daily lives. The news is filled with stories about the promise of personalized medicine, novel cancer treatments, the possibility of producing biofuels with the help ofgenetic engineering, and the use of genetic profiling in solving crimes. Other news stories report climate change and ecological disasters, new drug-resistant strains of the pathogens that cause tuberculosis and parasitic infections, and famine-crises in the world around us that are posing new challenges for biologists and their allies in the other sciences. On a personal level, many colleagues and I have missed our inspiring friend, the late Neil Campbell, even as our commitment to leadership in biological education has grown. Our changing world needs biologists and a scientifically literate citizenry as never be· fore, and we are committed to working toward that goal.
The New Coauthors
The Seventh Edition of BIOLOGY has been used by more students and instructors than any previous edition, remaining the most widely used college textbook in the sciences. With the privilege of sharing biology with so many students comes the responsibility of improving the book to serve the biology community even better. For that reason, Neil would have been delighted to see that this Eighth Edition fulfills our decade-long goal of expanding the author team. As biological discoveries proliferated, Neil and I realized that it was becoming harder than ever to make judicious decisions about which biological concepts are most im~ portant to develop in depth in an introductory textbook. We needed an author team with first-hand expertise across the bio-logical spectrum, and we wanted coauthorswho had honed their teaching values in the classroom. Our new coauthors-Lisa Urry, Michael Cain, Steve Wasserman, Peter Minorsky, and Rob Jack· son-represent the highest standards of scientific scholarship across a broad range of disciplines and a deep commitment to undergraduate teaching. As described on pages iv-v, their scientific expertise ranges from molecules to ecosystems, and the schools where they teach range from small liberal arts colleges to large universities. In addition, both Lisa and Peter, as major contributors to earlier editions, had prior experience working on the book. The six of us have collaborated unusually closely, starting with book-wide planning meetings and continuing with frequent exchanges of questions and advice as we worked on our chapters. For each chapter, the revising author, editors, and I together for· mulated a detailed plan; subsequently, my own role involved commenting on early drafts and polishing the final version. Together, we have strived to extend the book’s effectiveness for today’s students and instructors, while maintaining its core values.
