The Story of Human Hair

Why do humans have most of our hair on our heads, not our bodies? Why do we have so many varieties of hair color, thickness, and curliness? Dr. Tina Lasisi is a biological anthropologist whose work explores these evolutionary mysteries. In this episode, she shares her research into why humans have scalp hair as well as her insights on why curly hair is uniquely human.
