Biology: The Science of Life
Taught By Professor Stephen Nowicki, Ph.D., Cornell University,
Duke University

This intensive, 72-lecture course will give you the background and guidance to explore in depth the fundamental principles of how living things work—principles such as evolution by natural selection, the cellular structure of organisms, the DNA theory of inheritance, and other key ideas that will help you appreciate the marvelous diversity and complexity of life.
