In this two-minute sound segment, with the calls of a wood thrush in the background, a soil biologist discusses the probability that new species can be discovered in any handful of soil. He claims that when you pick up a handful of soil anywhere, whether it is in your backyard or in a forest, if you look at it closely enough, there will be organisms there that we have never seen before, especially microbial organisms. This site is an archive of a daily radio program called Pulse of the Planet, which provides its listeners with a portrait of Planet Earth, tracking the rhythms of nature, culture and science worldwide and blending interviews and extraordinary natural sound. The site also provides a written transcript of the broadcast.
