After consulting at the Los Angeles Zoo on a monkey with heart failure, Dr. Barbara Natterson-Horowitz discovered that animals experience many of the same health problems as humans -- from obesity and breast cancer to substance abuse and depression. She collaborated with science writer Kathryn Bowers to learn more. What can animals teach us about our health?
On the paleo-fantasy:
"One of the assumptions I had, I have to say, before this project was what others have called the paleo-fantasy -- that in the past and in nature things were disease-free and animals died of predation. But of course with a little closer thought, disease occurs everywhere."
