In 1912, Alfred Wegener prоpоsed thаt аt оne time аll the continents were amassed together in one supercontinent, which he called Pangea. Most scientists of his day discounted his theory, known as continental drift. He provided two main points of evidence to support his theory. First, if you cut out the shapes of the major land masses they roughly fit together. The second, and more powerful, argument was that several fossils of the same species have been found on several of the continents. It has also been shown that descendent of those species did diverge into new species on the different continents. This speciation is most likely caused by which evolutionary pressure?
