But it must be part of a dispersal system. So reflecting on a plant like ginkgo that was around in very different ecosystems when the dinosaurs were on the planet, that has been around for hundreds of millions of years, really puts our own species — let alone our own individual existence — into a broader context.It’s a bit like those diagrams that you see, where there’s a picture of the Milky Way and there’s a little sign that says, “You are here.” Well, it’s the same idea.
