Alfred Wegener and his theory.
In 1912, Alfred Wegener hypothesized about Continental Drift. He had an idea that at one time 200 million years ago. He found that, on different sides of the Atlantic, there were similar animals fossils. Wegener compared the east side of South America to the west side of Africa and found that they fit together like puzzle pieces. Some other evidence he used was climate, rocks, and other fossils. Though he was criticized and rejected from his theory at first, it was later accepted 20 years after his death in 1930.
