Final answer:
Wegener's evidence of continental drift included the presence of tropical plant fossils in South Africa.
Step-by-step explanation:
Wegener's evidence of continental drift included the presence of tropical plant fossils in South Africa, despite its relatively mild climate. This suggested that South Africa was once connected to a continent with a tropical climate. Additionally, Wegener used other evidence such as the congruence in shapes of continents, matching fossils found on different continents, and matching mountain ranges to support his theory of continental drift.
