The theory of continential drift----------
In the mid-twentieth century, the famous "theory of continental drift" was referred to as the "Taylor-Wegener hypothesis", although this terminology was not usually used. Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912.
The evidences of continental drift are described as follows:
Evidence that South America and Africa might once have been joined to each other came from the research and study of the German geographer, Alexander von Humboldt. He traveled throughout South America, Africa, and various parts of the world, collecting plant and animal specimens and studying geography and geology. He observed many similarities between South America and Africa in addition to the apparent suitable of continental coastlines. For example, von Humboldt noticed that the mountain ranges near Buenos Aires, Argentina, match mountain ranges found in South Africa.
