Did you ever think about the geographical perception of the world, a map with 7 continents presumably pops into your head instantaneously? Even though that image is correct to the modern-day, not a lot of people remember the map is continually shifting. A new country rises up every once in awhile, continental margins change due to climate change. But all that is a very trivial shift compared to what happened to our planet between 150-300 million years ago. These maps show how it changed over the years continuously and finally to the point where we are today.
Even though there was some speculation about the movement of continents back in the 16th century, this theory was left rejected and underdeveloped for almost 4 centuries for lack of any motive mechanism. However, some scientists lingered on the idea for a while after it was rejected in 1596 but were unable to back it up with enough scientific evidence. That was until Alfred Wegener’s paper was published in 1912.
Wegener was a geophysicist and meteorologist who finally made a decent breakthrough by figuring out that fossils of similar animals and plant fossils and similar rock formations from the same time period can be found on different continents. He was also the first to propose the term “continental drift”.
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.
