Last night's show was a wild ride through the realms of bacteria, other more bad-ass bacteria, protists, fungi, plants, and animals. Give 'er an ear here (27MB).
P.S. A belated welcome to Farmer Andrew Bryson, who journeyed deep into the Amazon with little more than a backpack in search of the fungi segment heard on last night's programme.
