Plants have transformed the surface of the earth and the contents of our atmosphere. To do this they've developed elaborate systems of roots and branches which (sometimes) follow uncanny mathematical patterns such as the Fibonacci sequence.

Our guest this week, Sandy Hetherington, leads Edinburgh's Molecular Palaeobotany and Evolution Group. They take a no-holds-barred approach to understanding plant development by combining genomics, fossil records, herbaria, and 3D modeling.
