Biology is grounded in 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 topics have been condensed and combined; for example, phylogenetic trees are presented in the various ways they are currently being developed by scholars, so instructors can adapt their teaching to the approach that works best in their classroom. The book also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Expert TA’s integrated solution comes with access to the OpenStax textbook and the online homework system at a cost to students of $35 per semester. Students can also access the electronic version of the book for free at OpenStax. Physical copies of the textbook are sold by OpenStax via Amazon for about the cost to print them (~$52).

“Expert TA is a great way to get a high quality problem set in front of the students and get their work graded almost instantly. I replaced the time I spent on grading with time talking with students. Research shows that the number one thing that most helps students succeed in college is personal interaction between the instructor and students.”
Chris Duston, Ph.D., Visiting Scholar at Stony Brook University, Stony Brook, NY
