When was the first scientific explanation of continental fossil matches proposed?
Quick Answer
A major explanation was proposed in the early 20th century, especially by Alfred Wegener in 1912.
The Full Story
Scientists had long noticed that fossils of the same species appeared on continents now separated by oceans. Alfred Wegener used these matches, along with matching rock types and climate evidence, to argue in 1912 that the continents had once been joined together. His explanation was controversial, because he could not yet provide a convincing mechanism for movement. Later plate tectonics supplied that mechanism and validated many of his observations.
