Cool Science Radio's interview with Thor Hanson who has written Buzz: The Nature and Necessity of Bees. In Buzz, he looks beyond the frenzied debates about dwindling bee populations to explore where bees come from and what makes them so remarkable. The story begins 125 million years ago, when a wasp first dared to feed pollen to its young. Bees helped spark an agricultural revolution, and have been crucial to advances in everything from medicine to industry, neuroscience to architecture. To this day, they are responsible for as much as a third of the foodstuffs we eat.
