Lesson Summary. Scientists had noticed that the coastlines of the continents had complementary shapes and could fit together. Alfred Wegener was the first person to propose that all the continents were once connected together in a supercontinent, known as Pangaea.
The mechanism for the breakup of Pangea is now explained in terms of plate tectonics rather than Wegenerâs outmoded concept of continental drift, which simply stated that Earthâs continents were once joined together into the supercontinent Pangea that lasted for most of geologic time.
