Explanation:

Alfred Wegener was a German scientist who theorized in 1912 that continents were once connected.

To prove this he gave evidence of the perception that the continents (particularly South and America and Africa) could connect to each other like puzzle pieces.

He also showed the presence of similar fossils in areas that are now far apart which meant that the animals once lived in close proximity until the continents split-up.
