Description
What makes us human? And how did we get here? It's only human to want to know. These two renowned paleo-anthropologists have unlocked enormous gaps in our origin story. Each of them discovered some of the most significant prehistoric bones ever found in east Africa. For Donald Johanson it was Lucy. For Richard Leakey it was Turkana Boy. These skeletons helped explain how, why and when our ape ancestors evolved, grew bigger brains, and started walking on two legs. We hear the fascinating tales of their discoveries, but we also learn their personal origin stories, and what led each of them to try to solve some of humankind's greatest mysteries.

He further endeared himself to the public by refusing to patent the vaccine. He had no desire to profit personally from the discovery, but merely wished to see the vaccine disseminated as widely as possible. The interview with Dr. Salk featured in this episode was recorded in 1991. In it, Salk talks about being the child of uneducated immigrants, and carving his own path to medical school and eventually virology -- a specialty that didn't exist when he began as a researcher. He discusses the anti-semitic quotas he had to overcome, as well as the doubt and scorn of many of his peers. But he also describes the transformation and relief his polio vaccine brou by What It Takes®
