The Ginko (also known as Ginkgo Biloba) is one of the oldest living tree species in the world. It is the sole survivor of an ancient group of trees that date back to before dinosaurs roamed the Earth up to 66 million years ago. It is so ancient, the species is known as a 'living fossil'.
Extreme examples of the ginkgo's tenacity may be seen in Hiroshima, Japan, where six trees growing between 1–2 kilometres from the 1945 Atom Bomb explosion were among the few living organisms in the area to survive the blast. Although almost all other plants and animals in the area were killed, the ginkos, though charred, survived and were soon healthy again.
