Millions of years ago Pangaea is what was believed to be, and now has evidence to support, the first continent on earth. It is referred to as the super continent as all existing continents were connected to it. In Greek, Pangaea is defined as “all the earth”; the man who came up with theory was Alfred Wegener. Wegener had a PhD in astronomy but always had an interest in geoscience. “Wegener was browsing in the university library when he came across a scientific paper that listed fossils of identical plants and animals found on opposite sides of the Atlantic” (UCMP, Alfred Wegener). This paper sparked quite an interest for Wegener, and he began to research this topic extensively. He knew to prove this “crazy” theory he would have to be able to back it up with a lot of scientific evidence. As he began to look at the borders of all the continents he noticed that the borders could almost fit together like puzzle pieces. Next, he found similar fossils in different continents. How could tropical fossils like ferns be found in the North Pole where there is no possible way a tropical plant could possibly grow in the cold climate of the arctic regions? It didn’t add up for Wegener, he then believed that the climate was much different when Pangaea was around two hundred million years because of the different places animals were able to live at the time, then millions found as fossils where it would have been impossible for them to grow and survive in that geographical place due to climate, and resources needed to survive. So he has this evidence that at some point all these continents were connected, but how did they split apart was the biggest question asked. He decided to publish a book that explained his thinking behind the theory of “continental drift”. Many didn’t buy a word of the theory “continental drift” that Wegener was trying to prove, the fact that he had no idea how the continents split, ripped, or in some fashion formed the present-day...
