"As active scientists working in a wide variety of both basic and applied biology, we are fortunate to be part of a field that is not only fascinating but also changes rapidly. It is apparent not just in the time span since we started our careers-we see it every day when we open a newspaper or a scientific journal. As educators of both introductory and advanced-level students, we desire to convey our excitement about biology's dynamic nature.
This new edition of Life looks, and is, quite different from its predecessors. In planning the Eighth Edition, we focused on three fundamental goals, The first was to maintain and enhance what has worked well in the past-an emphasis on not just what we know but how we came to know it; the incorporation of exciting new discoveries; an art program distinguished by its beauty and clarity; plus a unifying theme, As should be the case in any biology textbook, that theme is evolution by natural selection, a 150-year-old idea that more than ever ties together the living world. We have been greatly helped in this endeavor by the addition of a new author, David Hillis, His knowledge and insights have been invaluable in developing our chapters on evolution, phylogeny, and diversity, and they permeatp thp rest of the book as well.
Our second goal has been to make Life more pedagogically accessible, From the bold new design to the inclusion of numerous learning aids throughout each chapter (see New Pedagogical Features), we have worked to make our writing consistently easy to follow as well as engaging.
Third, between editions we asked seven distinguished ecologists-ail of whom teach introductory biology-to provide detailed critiques of the Ecology unit. As a result of their extensive suggestions, Part Nine, Ecology, has a fresh organization (see The Nine Parts), And one of the seven, May Berenbaum, has agreed to join the Life author team for the Ninth Edition. The other six stalwarts are thanked in the "Reviewers of the Eighth Edition"section..." (David Sadava, Craig Heller, Gordon Orians, Bill Purves & David Hillis)
