What are three pieces Alfred werned?

Alfred Wegener is best known for his theory of continental drift, which proposed that continents were once a single landmass called Pangaea. He presented three key pieces of evidence to support his theory: the fit of the continents, particularly South America and Africa; fossil similarities across continents, such as the presence of the Mesosaurus in both South America and Africa; and geological similarities, including matching rock formations and mountain ranges on different continents. Despite initial skepticism, Wegener's ideas laid the groundwork for the development of plate tectonics.
