The First Forests

 

Andrew Luck Baker takes us to the dim and distant past, when trees first evolved on the planet.

New fossil discoveries in the United States have given scientists their first proper picture of what the earliest forests looked like - rather strange as it turned out.

The advent of forests was a momentous event in Earth history - transforming its atmosphere and climate.
