Detailed explanation-1: -Ginkgo biloba comes from the leaves of the ginkgo tree, one of the oldest living plant species. Dating back more than 200 million years, it is often referred to as “a living fossil.” Because its leaves resemble the maiden-hair fern, it is also known as the maidenhair tree.
Detailed explanation-2: -Not only has this exceptionally hardy species survived three mass extinction events over the past quarter of a billion years, but it was found to be the only surviving plant species near the epicenter of the August 6th, 1945 Hiroshima atomic bomb blast.
Detailed explanation-3: -The ginkgo (Ginkgo biloba) is a living fossil, with fossils similar to the modern plant dating back to the Permian, 270 million years ago. The closest living relatives of the clade are the cycads, which share with the extant G. biloba the characteristic of motile sperm.
Detailed explanation-4: -Fossils of Ginkgo leaves have been discovered that date back more than 200 million years.
