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!

96- Ancestors versus Human Population

Your number of ancestors double every generation. Two parents, four grandparents, and so on. If we compare these numbers to the total number of people alive on the planet as we go back in time, what do we find? And what do researchers say on the subject?
