That idea first began with Alfred Wegener (1880-1930) in 1912. He observed how the borders of some continentes fit well together and argued that the continents were once together in a single one, which broke and gave rise to the current configuration. This also explained easily some fossil distribuition in weird patterns that seemed to continue between continents
