Evolutionary Medicine - David Graham at TEDxBillings

Why is it we get certain illnesses or diseases? In the modern world, we can talk about stress, diet and just plain bad luck but often these answers are disappointing. The real "why" behind these questions in medicine can only be answered from an evolutionary perspective. After generations of evolution, why are our bodies still vulnerable to illness and disease? There is a paragraph missing at the end of each entry in standard medical textbooks, a paragraph that may more deeply let us understand why we are getting ill and perhaps what can be done about it.

David Graham, MD, trained in Ann Arbor and Los Angeles. For the last 8 years he has lived in Montana with his wife Heather and their many varied animals. While practicing primary care, he has begun to ask why his patients get sick. Why, after thousands of years of evolution, are we left to suffer from disease and illness?

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
