One day in 1910, a young German meteorologist, Wegener, was lying on a hospital bed, his eyes turned to a map of the world on the wall, and he accidentally discovered that the western coastline of Africa and the eastern coastline of South America were so matched like a paper torn apart, you can put them together again, and a thought flashed in Wegener's mind: the two continents were originally a single whole piece, but only later did they rupture and drift apart, forming the way they are now
The paleontological species (plant fossils and animal fossils) are almost identical on both coasts of the Atlantic Ocean
