Your Inner Fish
A Journey into the 3.5-Billion Year History of the Human Body

Teaching Tools

In Your Inner Fish, Neil Shubin tells the story of evolution by tracing the organs of the human body back millions of years, long before the first creatures walked the earth. By examining fossils and DNA, Shubin shows us that our hands actually resemble fish fins, our head is organized like that of a long-extinct jawless fish, and major parts of our genome look and function like those of worms and bacteria. We have compiled the figures from the book into a deck of PowerPoint slides for use in the classroom.
