Closely related species are put in a group called. Scientists put species into groups that are based on similarity so that those millions of species do not seem so overwhelming. People rely on their Groups that are close together, like plants and animals, are much more closely related than groups that are far apart, like plants and bacteria. Do you see how.

Closely related species are put in a group called. Researchers generally agree that among the living animals in this group, humans are most closely related to chimpanzees, judging from comparisons of anatomy and genetics. If life is the result of "descent with modification," as Charles Darwin put it, we can try to represent its history as a kind of family tree derived from.

Allan Tobin's undergraduate degree from MIT is in literature and biology and his doctoral degree is in biophysics with an emphasis on physical biochemistry. For more than 35 years he has taught introductory courses in general biology, cell biology, molecular biology, developmental biology, and neuroscience.

He is the recipient of the U. Los Angeles Faculty Teaching and Service Award and is regarded as an excellent and highly interactive teacher. Jennie Dusheck has an undergraduate degree in zoology from U. Berkeley and her master's degree is also in zoology. She also holds a certificate in science writing from U. Dusheck has written for "Science News," "Science Magazine," and other publications. From to she was the Principal Editor at U.

As a biologist she has studied the effects of light intensity on bird song, social behavior in field mice, food preferences of deer, cattle and skipper butterflies as well as axis formation in Xenopus laevis. Tobin , Jennie Dusheck. Experiments are the plot that holds the story of biology together. In this important revision, the authors continue to use thought-provoking chapter-opening stories to engage students in the process of science.

At the same time, they focus on making the text more accessible through streamlined coverage fewer pages in this edition and a refined organization and design. New features make it easier for students to remember the main ideas. For example, Key Questions begin each chapter, main headings are numbered to make it easier for students to locate previously read information, and Chapter Summaries are organized around Key Questions. All these features provide consistency throughout each chapter.

Student support is also a main focus. A student CD-ROM, BiologyNow, packaged FREE with each copy of the text includes questions created around the text's opening stories and uses diagnostic pre-tests to generate a personalized learning plan for each student.

Updated throughout, the Third Edition captures the terrific excitement of current 21st century science and is accompanied by powerful new learning tools that expand the text's themes.
