Trees That Aren't Programmed to Die

Aging is not the reason Gingko trees die. They are not genetically programmed to age, and they use several mechanisms to continue to survive for hundreds of years. This means they haven’t evolved much for hundreds of thousands of years, making them living fossils of what the world was like 200 million years ago.
