Question

how did wegener explain why fossils of land animals were found on continents that are across oceans from one another?
animals evolved separately on each continent.
land bridges existed between the continents.
animals swam across the ocean to new continents.
continents were once one landmass and have drifted apart.

Explanation:

Wegener proposed the theory of continental drift. He believed that all continents were once joined together as a single super - continent called Pangaea and over time, they drifted apart. This explains why similar land - animal fossils are found on distant continents.
