A TED-Ed Animation Explaining How Studying Domesticated Dogs Helped Treat Diabetes

In the latest animation by TED-Ed, educator Duncan C. Ferguson explains how the study of man’s best friend helped scientists discover the causes of diabetes and eventually helped treat the deadly disease.

In 1890, the German scientists [Joseph] von Mering and [Oskar] Minkowski demonstrated that removing a dog’s pancreas caused it to develop all of the signs of diabetes, thus establishing the organ’s central role in the disease.
