The idea that coastlines of continents fit together like puzzle - pieces was noticed long before more scientific evidence came about. Early explorers traveling from Europe and Asia to the Americas made early observations about the shapes of the continents. Geologists examining the fossil record, Alfred Wegener's proposal of continental drift, and satellite pictures are later developments in the understanding of continental drift. The initial noticing of the puzzle - piece fit of coastlines happened when early explorers traveled.
