The Evolution of Trees
Summary
Melvyn Bragg is joined by Jenny McIlwain, Christopher Berry, and Bill Baker to explore the evolutionary history of trees. They discuss the emergence of the first forests in the Devonian period, how trees engineered ecosystems and altered Earth's climate, and the use of genetic data to map the tree of life. The conversation also covers convergent evolution, such as island woodiness, and current research into tree resilience against climate change.
