Human Biology Was designed to integrate the topics of health,wellness,and the environment in a way that perfectly suits the nonmajors' Course. With this purpose in min,the authors identified several goals that guided them through the revision of Human Biolgy Twelfth edition.- Hemeostasis and Evolution coverage increased - Genetics of human disease coverage expanded - Case Studies revised to include discussions of medical procedures and the genetics of human disease - Applications added to enhance the relevancy of content for student - Media assets intregated in textbook and connext tm Biology. Increased coverage of Homeostasis and Evolution Many of the connecting the concepts features at the end of each section address homeostasis and direct students to other sections of the textbook to emphasize how the bodysystems interact to make homeostasis possible.Throughout the textbook,new evolutionary diagrams have been added to indicate the importance of evolution in the study of human biology. In addition, many of the Connections and Misconceptions boxes now relate to evolutionary themes.
