Why is Ginkgo biloba and Metasequoia called living fossils?

1. What is a living fossil?

Living fossils are organisms that have not evolved themselves during the long process of historical evolution, and their growth process has not been interrupted, and they are still surviving tenaciously to this day. Because these creatures act like recorders on Earth, they provide great help to scientists' research.

2. Ginkgo and Metasequoia

The ginkgo tree, also known as the white fruit tree, appeared 270 million years ago. Later, most of the ginkgo trees became extinct like the dinosaurs. Only a few of them are preserved in some parts of my country. It is known as a "living fossil" and the "panda" among plants.

Metasequoia first appeared in the Cretaceous period of the Mesozoic Era and is a precious relict plant that survived the Quaternary glacial catastrophe.
