If you ever think about our geographical perception of the world, a map with 7 continents probably pops into your head instantaneously. Even though that image is correct to the present day, not a lot of people tend to remember the map is constantly shifting. A new country pops up every once in a while, continental borders change due to climate change. But all that is a very insignificant shift compared to what happened to our planet between 150-300 million years ago. These maps reveal how it changed over the years until it got to the point that resembles the world as we know it today.
It’s hard to believe but a long time ago, the world as we know it might have been one huge continent
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.
There’s a theory that it assembled from previous continental units approximately 335 million years ago
The enormous continent began to break up again sometime about 175 million years ago
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”.
The theory that continents have moved away from each other was first introduced by Abraham Ortelius in 1596
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.
