Final answer:
The discovery of similar fossils in South America and Africa supports the Theory of Plate Tectonics.
Step-by-step explanation:
One piece of evidence that supports the Theory of Plate Tectonics is the discovery of similar fossils in both South America and Africa. This suggests that these landmasses were once connected and have since separated due to the movement of tectonic plates. The presence of similar fossils in two separate continents provides strong evidence for the theory of plate tectonics.
