Biology is a fascinating subject which is well worth exploring. Its scope stretches from individual DNA strands and viruses to blue whales, metapopulations and the biosphere. We will shine the spotlight on a different biological concept in every episode. Topics I've covered in the past include the origins of cell theory, Dollo's law and the Anthropocene; however, there is still plenty more to discover. Our focus will range from the very smallest scales to the very largest; from virions to the Gaia hypothesis. So come and explore the fascinating world of biology, one episode at a time!
