B.4 Natural Selection & Evolution of Populations
Unrestricted Use

Rating
0.0 stars

How does urbanization affect nonhuman populations, and how can we minimize harmful effects? How does urbanization affect nonhuman populations, and how can we minimize harmful effects? This unit on natural selection and evolution of populations focuses on the phenomenon of increasing urbanization around the world and the impact of that change on nonhuman populations. Students investigate case studies that investigate fragmentation, poison, and proximity to humans as selection pressures that affect the relative fitness of individuals with particular anatomical, physiological, and behavioral traits in a population. Through investigations with complex data sets, they figure out how genetic diversity in a population allows populations to adapt to changes encountered in urban environments.

Students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Then they use coin tossing to determine the traits a mouse pup born to these parents possesses. Then they compare these physical features to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

Rating
0.0 stars

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.
