A recurring theme in Chris Packham’s series Earth is the timely coincidences that came with planetary events. Having just re-watched the third of the five part series, it is striking how the twin-track development of what later evolved into plants depended on some shared resources with what later became fungi. The proto-fungi extracted minerals from bare rock that nourished evolving plants, while the early plants gave glucose to their fungal partners. Without this leap in evolution, we would not exist today.
