B. The theory was created by Alfred Wegener.
C. Two forms of evidence are: 1) Fossil distribution - similar fossils are found on different continents now separated by oceans, suggesting they were once connected. 2) Geological - matching rock - formations and mountain ranges are found on different continents that could have been part of the same structure before drifting.
