What Darwin Never Knew
Learn the Science
EXAMINE DARWIN'S THEORY OF NATURAL SELECTION
One hundred and fifty years ago, Charles Darwin set forth his theory of evolution by natural selection, which became the foundation of our understanding of life on earth. Explore his insights with your students.
What Darwin Never Knew (Video)
Follow the path that led Darwin to his theory of evolution by natural selection, and his masterwork "On the Origin of Species." (Chapters 2-5, 29:48 min.)

Evolving Ideas: How Does Evolution Really Work? (Video)
Understand the process of evolution through natural selection by hearing from scientists who are researching hummingbirds. (6:39 min.)

Dogs and More Dogs (Lesson)
