Select your answer for: The Maidenhair tree (Ginkgo biloba) of Zhexiang, ______, which originated roughly 165,000,000 years ago in the Jurassic period, stands as the most ancient surviving tree species:
Show answer

Answer: C. China

Explanation

Ginkgo biloba, the Maidenhair tree native to China, originated during the Jurassic period. Fossil records place its evolutionary emergence roughly 165 million years ago. It is globally recognized as the most ancient surviving tree species without close living relatives. Ginkgo biloba is famous as a living fossil because it survived major extinction events. The species features unique fan-shaped leaves and exceptional resistance to urban pollution. Ancient specimens preserved in Chinese temple gardens protected the species from prehistoric extinction.

Botanists study Ginkgo biloba to understand early seed plant evolution and paleobotany. Urban landscapers plant Maidenhair trees widely due to their high resilience and golden foliage. Traditional medicine utilizes extracts from Ginkgo leaves for various therapeutic health applications. Option A is incorrect because Korea is not the native origin point of the Maidenhair tree. Option B is wrong because Japan received Ginkgo specimens historically from mainland China. Option D is inaccurate because Malaysia features tropical flora rather than ancient Ginkgo forests.
