On this episode of This Day In History, Tony and Armand sit down to discuss an important theory presented by German geophysicist, Alfred Wegener. On this day in 1912, Wegener presented his theory of continental drift explaining why look-alike animal and plant fossils, and similar rock formations, are found on different continents. Also, Alfred Vail demonstrates the forerunner to Morse code and Mother Teresa arrives in Calcutta, India. Join us for this episode of This Day In History!
