Cardiologist and evolutionary biologist Dr. Barbara Natterson-Horowitz describes herself as an innovator for human health. She is a professor at Harvard University's department of human evolutionary biology and a professor of medicine at UCLA. She's also the co-author of bestselling books Zoobiquity and Wildhood. Dr. Natterson-Horowitz studies a range of wild animals including lions and giraffes in their natural settings, observing their evolutionary adaptations, which then offer clues for potential solutions to common medical disorders in humans. She says the biology of some female animals has evolved over centuries to resist diseases that still claim the lives of women today.
