The discovery of similar fossils of marsupials across South America, Africa, Antarctica, India, and Australia supports the theory that a vast land bridge once connected those continents. This idea aligns with the concept of continental drift and the distribution of species prior to the breakup of the supercontinent Gondwana, which included these landmasses. Early marsupials being strong swimmers is less supported as a primary explanation for such widespread fossil evidence, and while the processes that occur today (uniformitarianism) are indeed applicable to geological history, they do not specifically explain the distribution of these fossils in the context provided.
