Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates. Age-structure diagrams and the demographic transition model can allow countries to plan for future growth. [10:18]

How quickly is the human population growing? If we look at worldwide human population growth from 10,000 BCE through to today, our growth looks like exponential growth. It increased very slowly at first, but later grew faster and faster as the population increased in size. Learn more about human population in this learning module produced by CK-12.
