The close fit between the coastlines of Africa and South America can be used as proof to support the theory given by Wegener.
Alfred Wegener is most remembered as the originator of the theory of continental drift by postulating in 1912 that the continents are gradually wandering around the Earth. Various discoveries, like paleomagnetism, gave strong support for continental drift, and thus forms a considerable groundwork for today's model of plate tectonics.
