Some scientists backed up that speculation but Alfred Wegner was the first to come up with quite a complete theory in 1912
Scientists most commonly tend to see similar fossils of various kinds as stronger evidence of continental drift and the complementary arrangement of the facing sides of continents such as South America and Africa, for example. Although, biology professor Matthew Wills claims that this map of conjoined continents is nowhere near as accurate as claimed as much of the continent existing for 300 million years has been subducted and a new crust has developed.
