On the NPR TED Radio Hour Sunday 27th of December 6pm

'Adaptation'

Christopher McDougall explores the mysteries of the human instinct to run: how did endurance help early humans survive and what urges from our ancient ancestors spur us on today?

Daniel Kish has been blind since he was 13 months old, but has learned to "see" using a form of echolocation.

The conversation continues with writer Rich Benjamin, who is an African-American man, moved into some of the whitest communities in America. Benjamin wanted to know -what's driving some white Americans to pick up and move to more homogeneous communities?

Janet Echelman found her true voice as an artist when her paints went missing - which forced her to look to an unorthodox new art material. Now she makes billowing, building-sized sculptures, made of natural and synthetic fibers.
