Pangaea
Continental drift
On December 1910 a young scientist named Alfred Weghener, hypothisis that at one point all of the contients were apart of one super continent called "Pangaea". The evidence came from the shape of the land, fossils, land forms, and the ancient ice age. The shape of the land was South America+Africa. Matching plant and animal fossils that have been found on different sides of the oceans. The land forms like mountain ranges, and rock formations have matched up to different continents. The theory of continental drift, was the theory that over time, the continents are drifted away from each other.
