What physical activity gives you joy? Whether it’s walking, running, dancing or swimming, your body evolved to do it. We are made for movement. But there’s a cost, as anyone with a sore neck or aching back knows. From the tiny muscles in our skin, which raise the hair on our arms, to the intricate mix of bone, blood vessels, and nerves in our neck, natural selection has struck a delicate and sometimes wacky balance between utility and form. In this episode, we explore how parts of the body - our muscles, neck and feet - came to be, and what forces prompted the evolution of efficient yet imperfect bodies.

Guests:

Kent Dunlap - Professor of biology at Trinity College in Hartford, Connecticut and author of “The Neck: A Natural and Cultural History”

Bonnie Tsui - Journalist and author of “On Muscle: The Stuff That Moves Us and Why It Matters”

Jeremy DeSilva - Anthropologist at Dartmouth College and author of “First Steps, How Upright Walking Made Us Human”

Featuring music by Dewey Dellay and Jun Miyake
