What clues were missing from Alfred wegeners puzzle?

Answer 1

Alfred Wegener's puzzle regarding continental drift lacked crucial evidence from geology and Paleontology, particularly the absence of a mechanism to explain how continents could move. He proposed that continents drifted through the ocean, but did not provide a satisfactory explanation for the forces driving this movement. Additionally, the lack of detailed fossil correlations and geological similarities across continents limited the acceptance of his theory until later advancements in plate tectonics provided the missing pieces.
