Solution

Ginkgo biloba earns the designation of a "living fossil" because it is the sole surviving member of its taxonomic group, while all other members of this group have become extinct and are known only from fossil records. A living fossil is a term used to describe a living species that bears a striking resemblance to a species known solely from fossils, often without any closely related living counterparts. This resemblance is usually based on physical similarities between two distinct species, one of which is extinct, and the other is extant. It's worth noting that "living fossil" is an informal, non-scientific term, primarily employed in popular media and discussions.
