Did you know that 300 years ago people had larger jaws? Why would this be the case and why is it important? Paul Ehrlich, the founding father of modern population sciences, is here to talk about his new book which is a bit of a diversion from his usual work – warning us to not have too many kids. This time, Ehrlich, along with co-author and orthodontist Sandra Kahn, explore the links between jaw size and an increased risk of heart disease, cancer, sleep apnea and hyperactivity. Today, Ehrlich discusses the evolutionary biology of jaws and talks about what people can do to reverse what he calls a “hidden epidemic.”
