Most of the major categories of adaptive behavior can be seen in all animals. This course begins with the evolution of behavior, the driver of nervous system evolution, reviewed using concepts developed in ethology, sociobiology, other comparative studies, and in studies of brain evolution. The roles of various types of plasticity are considered, as well as foraging and feeding, defensive and aggressive behavior, courtship and reproduction, migration and navigation, social activities and communication, with contributions of inherited patterns and cognitive abilities. Both field and laboratory based studies are reviewed; and finally, human behavior is considered within the context of primate studies.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Compare innate and learned behaviorDiscuss how movement and migration behaviors are a result of natural selectionDiscuss the different ways members of a population communicate with each otherGive examples of how species use energy for mating displays and other courtship behaviorsDifferentiate between various mating systemsDescribe different ways that species learn
