The link of the continents is from Wegener, and yes, V cited it, but it isn’t original to him, and it’s unnecessary for the rest of his thesis. He pointed out that the fault lines actually are a sort of moebius, circling the world twice, and revealing that it has been in the grip of a large external force, rather than the nice, slow, quiet drifting of Wegener’s fantasy.
The “Plate Tectonics Revolution” of the 1960s revived continental drift, but under that new name, offering very little new. Wegener’s idea that the trivial resemblance of part of the west coast of Africa with part of the east coast of South America meant that they must at one time be joined.
