What was Alfred wagener theory?

Alfred Wegener proposed the theory of continental drift in the early 20th century, suggesting that continents were once part of a single supercontinent called Pangaea. He argued that this landmass gradually broke apart and drifted to their current positions over millions of years. Wegener supported his theory with evidence from fossil distributions, geological similarities, and the fit of continental Coastlines. Despite its initial rejection, his ideas laid the groundwork for the later development of plate tectonics.
