Best Answer

Alfred Wegener (1880-1930) was a German geologist from the early 20th century, who theorized that continental land masses moved on the Earth's crust (Continental Drift), because in the past some of the now-separated lands were at one time joined together. Geologically and biologically, they shared the same past location.
