Evidence of continental drift
Alfred Wegener noticed that the coasts of western Africa and eastern south America could fit together, like a puzzle. This led him to believe that all the continents could interlock. Also, similar animal and plant fossils were fond on continents that were separated by a colossal ocean (Dive and Discover : History of Oceanography). This also provoked the idea that these continents were once united together.
