Wegener believe that there was once a single supercontinent, which he called Pangea (or Pangaea). He said that Pangea broke apart millions of years ago to form two large continents. He called the one in the northern hemisphere Laurasia and the one in the southern hemisphere Gondwanaland.lfred Wegener, who was educated to be a meteorologist and an Arctic climatologist, insisted that his theory was correct because of the evidence he saw. To support his ideas about continental drift, Wegener pointed to the similarities in the fossils of the southern continents.
The reaction to Alfred Wegener's Continental Drift Theory demonstrates that new ideas threaten the establishment, regardless of the century. Alfred Wegener was the scientist who proposed the Continental Drift Theory in the early twentieth century.Simply put, his hypothesis proposed that the continents had once been joined, and over time had drifted apart.egener did not even present Continental Drift as a proven theory. He knew he would need more support to convince others. His immediate goal was to have the concept openly discussed. These modest goals did not spare him.
