Summary
Misha Glenny and guests discuss the earliest evidence we have of the existence of trees and how even plants we might have on windowsills or as vegetables in gardens can and do, in the right conditions, evolve into trees. Since their emergence around 400 million years ago after low lying plants started to develop stronger stems and grow taller and more upright, trees have transformed our planet, so creating ecosystems, altering the atmosphere and setting the stage for the world as we know it today.
