Question

Quizplus · Accepted Answer

Stasis refers to a lack of change or evolution over a long period of time. In this scenario, the ginkgo tree has maintained similar characteristics for 270 million years, indicating stasis. Exaptation refers to the evolution of a trait for one purpose and later adaptation for another purpose. Radiation refers to the rapid diversification of a group of organisms. Sympatric speciation refers to the emergence of a new species without geographic isolation. Behavioral isolation refers to the lack of mating between two populations due to differences in behavior or courtship rituals. None of these options accurately describe the lack of change seen in the ginkgo tree.
